Trait TryNumFrom

pub trait TryNumFrom<T>: Sized {
    // Required method
    fn try_num_from(_: T) -> Option<Self>;
}

Just like TryFrom, but for numeric types not supported by the Rust’s std.

Required Methods

fn try_num_from(_: T) -> Option<Self>

Casts between numeric types.

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.
