Trait TryFromPrimitive

pub trait TryFromPrimitive: Sized {
    type Primitive: Copy + Eq + Debug;
    type Error;

    const NAME: &'static str;

    // Required method
    fn try_from_primitive(number: Self::Primitive) -> Result<Self, Self::Error>;
}

Required Associated Constants

const NAME: &'static str

Required Associated Types

type Primitive: Copy + Eq + Debug

type Error

Required Methods

fn try_from_primitive(number: Self::Primitive) -> Result<Self, Self::Error>

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.
