Struct InContext

pub struct InContext<'a, D: Contextual> { /* private fields */ }

A short-term binding of Context and any immutable object of a type that implements the Contextual trait.

The purpose of this type is to allow a transparent read access to shared data, like names etc. To prevent coarse-grained locking, Context is internally represented by a ContextHandle; however, Context can’t be modified through InContext.

Implementations

impl<D: Contextual> InContext<'_, D>

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

where F: FnOnce(&D, &Context) -> T,

pub fn same_context(&self, other: &Self) -> bool

pub fn get_context(&self) -> &ContextHandle

pub fn get_thing(&self) -> &D
