Trait hybrid_array::FromFn

pub trait FromFn<T>: Sized {
    // Required methods
    fn from_fn<F>(cb: F) -> Self
       where F: FnMut(usize) -> T;
    fn try_from_fn<E, F>(cb: F) -> Result<Self, E>
       where F: FnMut(usize) -> Result<T, E>;
}

Construct an array type from the given generator function.

Required Methods

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

where F: FnMut(usize) -> T,

Create array using the given generator function for each element.

fn try_from_fn<E, F>(cb: F) -> Result<Self, E>

where F: FnMut(usize) -> Result<T, E>,

Create an array using the given generator function for each element, returning any errors which are encountered in the given generator.
