Trait TryFrom

Source

pub trait TryFrom<T>: Sized {
    type Err;

    // Required method
    fn try_from(_: T) -> Result<Self, Self::Err>;
}

Required Associated Types§

type Err

Required Methods§

fn try_from(_: T) -> Result<Self, Self::Err>

Dyn Compatibility§

This trait is not dyn compatible.

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