Trait TryExt

pub trait TryExt {
    type Output;
    type Error;
    type Map<U>: TryExt<Output = U, Error = Self::Error>;

    // Required methods
    fn from_output(o: Self::Output) -> Self;
    fn branch<U>(self) -> ControlFlow<Self::Map<U>, Self::Output>;
}

Required Associated Types

type Output

type Error

type Map<U>: TryExt<Output = U, Error = Self::Error>

Required Methods

fn from_output(o: Self::Output) -> Self

fn branch<U>(self) -> ControlFlow<Self::Map<U>, Self::Output>

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.
