Struct Breadcrumb

pub struct Breadcrumb {
    pub timestamp: Annotated<Timestamp>,
    pub ty: Annotated<String>,
    pub category: Annotated<String>,
    pub level: Annotated<Level>,
    pub message: Annotated<String>,
    pub data: Annotated<Object<Value>>,
    pub event_id: Annotated<EventId>,
    pub other: Object<Value>,
}

The Breadcrumbs Interface specifies a series of application events, or “breadcrumbs”, that occurred before an event.

An event may contain one or more breadcrumbs in an attribute named breadcrumbs. The entries are ordered from oldest to newest. Consequently, the last entry in the list should be the last entry before the event occurred.

While breadcrumb attributes are not strictly validated in Sentry, a breadcrumb is most useful when it includes at least a timestamp and type, category or message. The rendering of breadcrumbs in Sentry depends on what is provided.

The following example illustrates the breadcrumbs part of the event payload and omits other attributes for simplicity.

{
  "breadcrumbs": {
    "values": [
      {
        "timestamp": "2016-04-20T20:55:53.845Z",
        "message": "Something happened",
        "category": "log",
        "data": {
          "foo": "bar",
          "blub": "blah"
        }
      },
      {
        "timestamp": "2016-04-20T20:55:53.847Z",
        "type": "navigation",
        "data": {
          "from": "/login",
          "to": "/dashboard"
        }
      }
    ]
  }
}

Fields

timestamp: Annotated<Timestamp>

The timestamp of the breadcrumb. Recommended.

A timestamp representing when the breadcrumb occurred. The format is either a string as defined in RFC 3339 or a numeric (integer or float) value representing the number of seconds that have elapsed since the Unix epoch.

Breadcrumbs are most useful when they include a timestamp, as it creates a timeline leading up to an event.

ty: Annotated<String>

The type of the breadcrumb. Optional, defaults to default.

• default: Describes a generic breadcrumb. This is typically a log message or user-generated breadcrumb. The data field is entirely undefined and as such, completely rendered as a key/value table.

• navigation: Describes a navigation breadcrumb. A navigation event can be a URL change in a web application, or a UI transition in a mobile or desktop application, etc.

  Such a breadcrumb’s data object has the required fields from and to, which represent an application route/url each.

• http: Describes an HTTP request breadcrumb. This represents an HTTP request transmitted from your application. This could be an AJAX request from a web application, or a server-to-server HTTP request to an API service provider, etc.

  Such a breadcrumb’s data property has the fields url, method, status_code (integer) and reason (string).

category: Annotated<String>

A dotted string indicating what the crumb is or from where it comes. Optional.

Typically it is a module name or a descriptive string. For instance, ui.click could be used to indicate that a click happened in the UI or flask could be used to indicate that the event originated in the Flask framework.

level: Annotated<Level>

Severity level of the breadcrumb. Optional.

Allowed values are, from highest to lowest: fatal, error, warning, info, and debug. Levels are used in the UI to emphasize and deemphasize the crumb. Defaults to info.

message: Annotated<String>

Human readable message for the breadcrumb.

If a message is provided, it is rendered as text with all whitespace preserved. Very long text might be truncated in the UI.

data: Annotated<Object<Value>>

Arbitrary data associated with this breadcrumb.

Contains a dictionary whose contents depend on the breadcrumb type. Additional parameters that are unsupported by the type are rendered as a key/value table.

event_id: Annotated<EventId>

Identifier of the event this breadcrumb belongs to.

Sentry events can appear as breadcrumbs in other events as long as they have occurred in the same organization. This identifier links to the original event.

other: Object<Value>

Additional arbitrary fields for forwards compatibility.

Trait Implementations

impl Clone for Breadcrumb

fn clone(&self) -> Breadcrumb

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Breadcrumb

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Breadcrumb

fn default() -> Breadcrumb

Returns the “default value” for a type.

impl Empty for Breadcrumb

fn is_empty(&self) -> bool

Returns whether this value is empty.

fn is_deep_empty(&self) -> bool

Returns whether this value is empty or all of its descendants are empty.

impl FromValue for Breadcrumb

fn from_value(__value: Annotated<Value>) -> Annotated<Self>

Creates a meta structure from an annotated boxed value.

impl IntoValue for Breadcrumb

fn into_value(self) -> Value

Boxes the meta structure back into a value.

fn serialize_payload<S>( &self, __serializer: S, __behavior: SkipSerialization, ) -> Result<S::Ok, S::Error>

where Self: Sized, S: Serializer,

Efficiently serializes the payload directly.

fn extract_child_meta(&self) -> MetaMap

where Self: Sized,

Extracts children meta map out of a value.

fn extract_meta_tree(value: &Annotated<Self>) -> MetaTree

where Self: Sized,

Extracts the meta tree out of annotated value.

impl PartialEq for Breadcrumb

fn eq(&self, other: &Breadcrumb) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ProcessValue for Breadcrumb

fn value_type(&self) -> EnumSet<ValueType>

Returns the type of the value.

fn process_value<P>( &mut self, __meta: &mut Meta, __processor: &mut P, __state: &ProcessingState<'_>, ) -> ProcessingResult

where P: Processor,

Executes a processor on this value.

fn process_child_values<P>( &mut self, __processor: &mut P, __state: &ProcessingState<'_>, ) -> ProcessingResult

where P: Processor,

Recurses into children of this value.
