Struct async_local::LocalRef

pub struct LocalRef<'id, T: Sync + 'static> { /* private fields */ }

A thread-safe pointer to a thread-local Context constrained by a “generative” lifetime brand that is invariant over the lifetime parameter and cannot be coerced into 'static

Implementations

impl<'id, T> LocalRef<'id, T>

where T: Sync + 'static,

pub fn with_blocking<F, R>(self, f: F) -> JoinHandle<R>

where F: for<'a> FnOnce(LocalRef<'a, T>) -> R + Send + 'static, R: Send + 'static,

Available on crate features tokio-runtime or barrier-protected-runtime only.

A wrapper around tokio::task::spawn_blocking that safely constrains the lifetime of LocalRef

Trait Implementations

impl<'id, T> Clone for LocalRef<'id, T>

where T: Sync + 'static,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'id, T: Debug + Sync + 'static> Debug for LocalRef<'id, T>

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

Formats the value using the given formatter.

impl<'id, T> Deref for LocalRef<'id, T>

where T: Sync,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'id, T: Hash + Sync + 'static> Hash for LocalRef<'id, T>

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<'id, T: Ord + Sync + 'static> Ord for LocalRef<'id, T>

fn cmp(&self, other: &LocalRef<'id, T>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<'id, T: PartialEq + Sync + 'static> PartialEq for LocalRef<'id, T>

fn eq(&self, other: &LocalRef<'id, T>) -> 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.

impl<'id, T: PartialOrd + Sync + 'static> PartialOrd for LocalRef<'id, T>

fn partial_cmp(&self, other: &LocalRef<'id, T>) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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