Struct devtools_wire_format::spans::SpanEvent

pub struct SpanEvent {
    pub event: Option<Event>,
}

A span event

Span events are emitted whenever a span lifecycle event happens and are thus rather low-level by nature.

Fields

event: Option<Event>

Implementations

impl SpanEvent

pub fn new_span( at: Timestamp, id: &Id, metadata: &'static Metadata<'static>, fields: Vec<Field>, parent: Option<Id> ) -> Self

pub fn enter_span(at: Timestamp, id: &Id, thread_id: u64) -> Self

pub fn exit_span(at: Timestamp, id: &Id, thread_id: u64) -> Self

pub fn close_span(at: Timestamp, id: &Id) -> Self

pub fn span_recorded(id: &Id, fields: Vec<Field>) -> Self

Trait Implementations

impl Clone for SpanEvent

fn clone(&self) -> SpanEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpanEvent

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

Formats the value using the given formatter.

impl Default for SpanEvent

fn default() -> Self

Returns the “default value” for a type.

impl Message for SpanEvent

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for SpanEvent

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

This method tests for self and other values to be equal, and is used by ==.

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

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