Struct StreamId 

pub struct StreamId {
    pub value: u64,
}

Unique identifier that can represent a stream based on the current thread id.

Fields

value: u64

The value representing the thread id.

Implementations

impl StreamId

pub fn executes<F, T>(self, f: F) -> T

where F: FnOnce() -> T,

Executes f on this stream, restoring the previous stream afterward.

The previous StreamId is saved before the call and restored on return — including on unwind — so the caller never has to manage raw swap pairs.

pub fn current() -> StreamId

Get the current thread id.

pub unsafe fn swap(stream: StreamId) -> StreamId

Swap the current stream id for the given one.

Safety

Unknown at this point, don’t use that if you don’t know what you are doing.

Trait Implementations

impl Clone for StreamId

fn clone(&self) -> StreamId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StreamId

fn deserialize<__D>( __deserializer: __D, ) -> Result<StreamId, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StreamId

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

Formats the value using the given formatter.

impl Hash for StreamId

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

where __H: Hasher,

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 Ord for StreamId

fn cmp(&self, other: &StreamId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StreamId

fn eq(&self, other: &StreamId) -> 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 PartialOrd for StreamId

fn partial_cmp(&self, other: &StreamId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StreamId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
