Trait CastFrom 

pub trait CastFrom<T> {
    // Required method
    fn cast_from(value: T) -> Self;
}

Cast from one type to another.

Mirrors From but with casting semantics. CastFrom<T> for U means “U can be created from T via cast”.

Example

use casting::CastFrom;

let x: u8 = 42;
let y = u16::cast_from(x);
assert_eq!(y, 42u16);

Required Methods

fn cast_from(value: T) -> Self

Casts value from type T to Self.

This method performs a numeric conversion using the as keyword.

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.
