Trait Try 

pub trait Try {
    type Output;
    type Residual;

    // Required methods
    fn from_output(output: Self::Output) -> Self;
    fn from_residual(residual: Self::Residual) -> Self;
    fn branch(self) -> ControlFlow<Self::Residual, Self::Output>;
}

Clone of std::ops::Try.

Implementing this trait is not permitted outside of rayon.

Required Associated Types

type Output

type Residual

Required Methods

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

fn from_residual(residual: Self::Residual) -> Self

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
