Struct console_api::async_ops::AsyncOp

pub struct AsyncOp {
    pub id: Option<Id>,
    pub metadata: Option<MetaId>,
    pub source: String,
    pub parent_async_op_id: Option<Id>,
    pub resource_id: Option<Id>,
}

An async operation.

An async operation is an operation that is associated with a resource This could, for example, be a a read or write on a TCP stream, or a receive operation on a channel.

Fields

id: Option<Id>

The async op’s ID.

This uniquely identifies this op across all currently live ones.

metadata: Option<MetaId>

The numeric ID of the op’s Metadata.

This identifies the Metadata that describes the tracing span corresponding to this async op. The metadata for this ID will have been sent in a prior RegisterMetadata message.

source: String

The source of this async operation. Most commonly this should be the name of the method where the instantiation of this op has happened.

parent_async_op_id: Option<Id>

The ID of the parent async op.

This field is only set if this async op was created while inside of another async op. For example, tokio::sync’s Mutex::lock internally calls Semaphore::acquire.

This field can be empty; if it is empty, this async op is not a child of another async op.

resource_id: Option<Id>

The resources’s ID.

Trait Implementations

impl Clone for AsyncOp

fn clone(&self) -> AsyncOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AsyncOp

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

Formats the value using the given formatter.

impl Default for AsyncOp

fn default() -> Self

Returns the “default value” for a type.

impl Message for AsyncOp

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, 

Encodes the message to a buffer.

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

Encodes the message to a newly allocated buffer.

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

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

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

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, 

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, 

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

impl PartialEq<AsyncOp> for AsyncOp

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

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

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

This method tests for !=.
