Struct Request

pub struct Request<'a>(/* private fields */);

Request supports generic, type-driven access to data.

This type is based on the unstable request type in std::error and it works in pretty much the exact same way.

Implementations

impl<'a> Request<'a>

pub fn provide_value<T>(&mut self, value: T) -> &mut Self

where T: 'static,

Provide a value or other type with only static lifetimes.

pub fn provide_value_with<T>(&mut self, fulfil: impl FnOnce() -> T) -> &mut Self

where T: 'static,

Provide a value or other type with only static lifetimes computed using a closure.

pub fn provide_ref<T: ?Sized + 'static>(&mut self, value: &'a T) -> &mut Self

Provide a reference. The referee type must be bounded by 'static, but may be unsized.

pub fn provide_ref_with<T: ?Sized + 'static>( &mut self, fulfil: impl FnOnce() -> &'a T, ) -> &mut Self

Provide a reference computed using a closure. The referee type must be bounded by 'static, but may be unsized.

pub fn would_be_satisfied_by_value_of<T>(&self) -> bool

where T: 'static,

Check if the Request would be satisfied if provided with a value of the specified type. If the type does not match or has already been provided, returns false.

pub fn would_be_satisfied_by_ref_of<T>(&self) -> bool

where T: ?Sized + 'static,

Check if the Request would be satisfied if provided with a reference to a value of the specified type. If the type does not match or has already been provided, returns false.
