Trait TupleDefault 

pub trait TupleDefault {
    // Required method
    fn tuple_default() -> Self;
}

A trait for creating default instances of tuples.

Part of the tuplities crate.

Required Methods

fn tuple_default() -> Self

Returns the default value of the tuple.

Examples

use tuplities_default::TupleDefault;

let default_tuple: (i32, String, f64) = <(i32, String, f64)>::tuple_default();

assert_eq!(default_tuple, (0, String::new(), 0.0));

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.
