Trait FromResidual 

pub trait FromResidual<R = <Self as Try>::Residual> {
    // Required method
    fn from_residual(residual: R) -> Self;
}

Used to specify which residuals can be converted into which core::ops::Try types.

see ::core::ops::FromResidual

Required Methods

fn from_residual(residual: R) -> Self

Constructs the type from a compatible Residual type.

see ::core::ops::FromResidual::from_residual()

Dyn Compatibility

This trait is not dyn compatible.

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