Trait wlan_hw_sim::event::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>;

    // Provided methods
    fn unwrap(self) -> Self::Output
       where Self: Sized { ... }
    fn expect(self, message: impl Display) -> Self::Output
       where Self: Sized { ... }
}

Divergent (fallible) types.

This trait abstracts the branching of types that represent independent outputs and non-outputs (errors). Such types must be constructible from these variants and queried for a corresponding control flow.

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>

Provided Methods

fn unwrap(self) -> Self::Output

where Self: Sized,

fn expect(self, message: impl Display) -> Self::Output

where Self: Sized,

Object Safety

This trait is not object safe.
