Trait FromDefault 

pub trait FromDefault<T>: Sized {
    // Required methods
    fn from_default(default: T) -> Self;
    fn display_default(default: T) -> impl Display;
}

A type which can be constructed from a default value.

Required Methods

fn from_default(default: T) -> Self

Creates this value from a default value.

fn display_default(default: T) -> impl Display

Writes the default value to a string.

Dyn Compatibility

This trait is not dyn compatible.

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