Struct AsyncContextDescriptor 

pub struct AsyncContextDescriptor {
    pub iid: Option<u64>,
    pub name: Option<String>,
    pub kind: Option<String>,
    pub parent_iid: Option<u64>,
}

Describes an async context referenced by TaskContext.async_id: a stackful unit of execution that is not an OS thread (goroutine, fiber, coroutine).

Fields

iid: Option<u64>

Interning key, equal to the TaskContext.async_id it describes. Starts from 1, 0 is the same as “not set”.

name: Option<String>

A human-readable name for this specific context, e.g. “worker-7”.

kind: Option<String>

The kind of async context, e.g. “goroutine”, “fiber”.

parent_iid: Option<u64>

iid of the structural parent AsyncContextDescriptor, if any.

Implementations

impl AsyncContextDescriptor

pub fn iid(&self) -> u64

Returns the value of iid, or the default value if iid is unset.

pub fn name(&self) -> &str

Returns the value of name, or the default value if name is unset.

pub fn kind(&self) -> &str

Returns the value of kind, or the default value if kind is unset.

pub fn parent_iid(&self) -> u64

Returns the value of parent_iid, or the default value if parent_iid is unset.

Trait Implementations

impl Clone for AsyncContextDescriptor

fn clone(&self) -> AsyncContextDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AsyncContextDescriptor

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

Formats the value using the given formatter.

impl Default for AsyncContextDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl Eq for AsyncContextDescriptor

impl Hash for AsyncContextDescriptor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for AsyncContextDescriptor

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for AsyncContextDescriptor

fn eq(&self, other: &AsyncContextDescriptor) -> 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.
