Struct index_ext::array::ArrayPrefix

pub struct ArrayPrefix<const N: usize>;

A marker struct for statically sized range to (..n).

This can make use of parameter deduction in many cases, for example if assigning the slice to a right hand side array pattern.

use index_ext::array::ArrayPrefix;
let [r, g, b] = buf[ArrayPrefix];

To slice off an array in the middle of a slice, utilize the common pattern of indexing twice.

use index_ext::array::ArrayPrefix;
let [u, v] = buf[1..][ArrayPrefix];

Trait Implementations
