Struct ThreadLocalCtxt

pub struct ThreadLocalCtxt { /* private fields */ }

A Ctxt that stores ambient state in thread local storage.

Frames fully encapsulate all properties that were active when they were created so can be sent across threads to move that state with them.

Implementations

impl ThreadLocalCtxt

pub fn new() -> Self

Create a new thread local store with fully isolated storage.

pub const fn shared() -> Self

Create a new thread local store sharing the same storage as any other ThreadLocalCtxt::shared.

Trait Implementations

impl Clone for ThreadLocalCtxt

fn clone(&self) -> ThreadLocalCtxt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ctxt for ThreadLocalCtxt

type Current = ThreadLocalCtxtFrame

The type of Props used in Ctxt::with_current.

type Frame = ThreadLocalCtxtFrame

The type of frame returned by Ctxt::open_root and Ctxt::open_push.

fn with_current<R, F: FnOnce(&Self::Current) -> R>(&self, with: F) -> R

Access the current context.

fn open_root<P: Props>(&self, props: P) -> Self::Frame

Create a frame that will set the context to just the properties in P.

fn open_push<P: Props>(&self, props: P) -> Self::Frame

Create a frame that will set the context to its current set, plus the properties in P.

fn enter(&self, frame: &mut Self::Frame)

Make the properties in a frame active.

fn exit(&self, frame: &mut Self::Frame)

Make the properties in a frame inactive.

fn close(&self, _: Self::Frame)

Close a frame, performing any shared cleanup.

fn open_disabled<P>(&self, props: P) -> Self::Frame

where P: Props,

Create a disabled frame.
