Trait Array

pub trait Array<T> {
    // Required method
    fn from_fn<F>(f: F) -> Self
       where F: FnMut(usize) -> T;

    // Provided method
    fn from_iter<I: Iterator<Item = T>>(iter: I) -> Self
       where Self: Sized { ... }
}

Implemented by arrays of different lengths.

Required Methods

fn from_fn<F>(f: F) -> Self

where F: FnMut(usize) -> T,

Creates array from a function of each component index.

Provided Methods

fn from_iter<I: Iterator<Item = T>>(iter: I) -> Self

where Self: Sized,

Creates an array from an iterator. Will fail if the iterator does not contain enough elements.

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.
