Crate generic_array[−][src]

This crate implements a structure that can be used as a generic array type.use Core Rust array types [T; N] can’t be used generically with respect to N, so for example this:

struct Foo<T, N> {
    data: [T; N]
}

won’t work.

generic-array exports a GenericArray<T,N> type, which lets the above be implemented as:

struct Foo<T, N: ArrayLength<T>> {
    data: GenericArray<T,N>
}

The ArrayLength<T> trait is implemented by default for unsigned integer types from typenum.

For ease of use, an arr! macro is provided - example below:

let array = arr![u32; 1, 2, 3];
assert_eq!(array[2], 3);

Re-exports

pub extern crate typenum;
pub use iter::GenericArrayIter;

Modules

arr

Implementation for arr! macro.

functional

Functional programming with generic sequences

iter

GenericArray iterator implementation.

sequence

Useful traits for manipulating sequences of data stored in GenericArrays

Macros

arr

Macro allowing for easy generation of Generic Arrays. Example: let test = arr![u32; 1, 2, 3];

Structs

GenericArray

Struct representing a generic array - GenericArray<T, N> works like [T; N]

Traits

ArrayLength

Trait making GenericArray work, marking types to be used as length of an array
