Function try_array_init

src/lib.rs:185–190

Initialize an array given an initializer expression that may fail. The initializer is given the index (between 0 and `N - 1` included) of the element, and returns a `Result ,`. It is allowed to mutate external state; we will always initialize from lower to higher indices. # Examples ```rust # #![allow(unused)] # extern crate array_init; # #[derive(PartialEq,Eq,Debug)] struct DivideByZero

(initializer: F)

/// assert_eq!(res,Err(DivideByZero));
/// ```
pub fn try_array_init<Err, F, T, const N: usize>(initializer: F) -> Result<[T; N], Err>
where
    F: FnMut(usize) -> Result<T, Err>,
{
    try_array_init_impl::<Err, F, T, N, 1>(initializer)
}
