Struct NelContext

pub struct NelContext {
    pub error_type: Annotated<String>,
    pub server_ip: Annotated<IpAddr>,
    pub elapsed_time: Annotated<u64>,
    pub phase: Annotated<NetworkReportPhases>,
    pub sampling_fraction: Annotated<f64>,
    pub other: Object<Value>,
}

Contains NEL report information.

Network Error Logging (NEL) is a browser feature that allows reporting of failed network requests from the client side. See the following resources for more information:

• W3C Editor’s Draft
• MDN

Fields

error_type: Annotated<String>

If request failed, the type of its network error. If request succeeded, “ok”.

server_ip: Annotated<IpAddr>

Server IP where the requests was sent to.

elapsed_time: Annotated<u64>

The number of milliseconds between the start of the resource fetch and when it was aborted by the user agent.

phase: Annotated<NetworkReportPhases>

If request failed, the phase of its network error. If request succeeded, “application”.

sampling_fraction: Annotated<f64>

The sampling rate.

other: Object<Value>

For forward compatibility.

Trait Implementations

impl Clone for NelContext

fn clone(&self) -> NelContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NelContext

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

Formats the value using the given formatter.

impl Default for NelContext

fn default() -> NelContext

Returns the “default value” for a type.

impl DefaultContext for NelContext

fn default_key() -> &'static str

The default key at which this context resides in Contexts.

fn from_context(context: Context) -> Option<Self>

Converts this context type from a generic context type.

fn cast(context: &Context) -> Option<&Self>

Casts a reference to this context type from a generic context type.

fn cast_mut(context: &mut Context) -> Option<&mut Self>

Casts a mutable reference to this context type from a generic context type.

fn into_context(self) -> Context

Boxes this context type in the generic context wrapper.

impl Empty for NelContext

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 NelContext

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

Creates a meta structure from an annotated boxed value.

impl IntoValue for NelContext

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 NelContext

fn eq(&self, other: &NelContext) -> 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 NelContext

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.
