Trait CombineReaders

pub trait CombineReaders {
    type ToBeRead<'b>;

    // Required methods
    fn read<U>(&self, f: impl FnOnce(Self::ToBeRead<'_>) -> U) -> U;
    async fn wait_for_update(&mut self) -> &mut Self;
}

Allows combining (nearly) arbitrary amounts of Readers, ExclusiveReaders or InitializedReaders.

Required Associated Types

type ToBeRead<'b>

The (tuple) value that will be read from the combined readers.

Required Methods

fn read<U>(&self, f: impl FnOnce(Self::ToBeRead<'_>) -> U) -> U

Reads a tuple of values from all combined readers in the provided function.

async fn wait_for_update(&mut self) -> &mut Self

Observes the combined readers for updates.

Will return if any of the readers is updated.

This returns &mut Self to allow chaining a call to read.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
