Struct relay_protocol::Meta

pub struct Meta(/* private fields */);

Meta information for a data field in the event payload.

Implementations

impl Meta

pub fn from_error<E: Into<Error>>(err: E) -> Self

From an error

pub fn original_length(&self) -> Option<usize>

The original length of this field, if applicable.

pub fn set_original_length(&mut self, original_length: Option<usize>)

Updates the original length of this annotation.

pub fn iter_remarks(&self) -> impl Iterator<Item = &Remark>

Iterates all remarks on this field.

pub fn clear_remarks(&mut self)

Clears all remarks

pub fn add_remark(&mut self, remark: Remark)

Adds a remark.

pub fn iter_errors(&self) -> impl Iterator<Item = &Error>

Iterates errors on this field.

pub fn add_error<E: Into<Error>>(&mut self, err: E)

Mutable reference to errors of this field.

pub fn original_value(&self) -> Option<&Value>

Returns a reference to the original value, if any.

pub fn original_value_as_mut(&mut self) -> Option<&mut Value>

Returns a mutable reference to the original value, if any.

pub fn set_original_value<T>(&mut self, original_value: Option<T>)

where T: IntoValue,

Sets the original value.

pub fn take_original_value(&mut self) -> Option<Value>

Take out the original value.

pub fn has_errors(&self) -> bool

Indicates whether this field has errors.

pub fn is_empty(&self) -> bool

Indicates whether this field has meta data attached.

pub fn merge(self, other: Self) -> Self

Merges this meta with another one.

Trait Implementations

impl Clone for Meta

fn clone(&self) -> Meta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Meta

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

Formats the value using the given formatter.

impl Default for Meta

fn default() -> Meta

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Meta

fn deserialize<D>(deserializer: D) -> Result<Meta, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Meta

fn eq(&self, other: &Self) -> 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 Serialize for Meta

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
