hex.rs Generic array are commonly used as a return value for hash digests, so it's a good idea to allow to hexlify them easily. This module implements `std::fmt::LowerHex` and `std::fmt::UpperHex` traits. Example: ```rust # #[macro_use] # extern crate generic_array; # extern crate typenum; # fn main() { let array = arr![u8; 10, 20, 30]; assert_eq!(format!("{:x}", array), "0a141e"); # } ``` 3761 54 %

lib.rs This crate implements a structure that can be used as a generic array type. Core Rust array types `[T; N]` can't be used generically with respect to `N`, so for example this: ```rust{compile_fail} 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: ```rust use generic_array::{ArrayLength, GenericArray}; struct Foo<T, N: ArrayLength<T>> { data: GenericArray<T,N> } ``` The `ArrayLength<T>` trait is implemented by default for [unsigned integer types](../typenum/uint/index.html) from [typenum](../typenum/index.html): ```rust # use generic_array::{ArrayLength, GenericArray}; use generic_array::typenum::U5; struct Foo<N: ArrayLength<i32>> { data: GenericArray<i32, N> } # fn main() { let foo = Foo::<U5>{data: GenericArray::default()}; # } ``` For example, `GenericArray<T, U5>` would work almost like `[T; 5]`: ```rust # use generic_array::{ArrayLength, GenericArray}; use generic_array::typenum::U5; struct Foo<T, N: ArrayLength<T>> { data: GenericArray<T, N> } # fn main() { let foo = Foo::<i32, U5>{data: GenericArray::default()}; # } ``` For ease of use, an `arr!` macro is provided - example below: ``` # #[macro_use] # extern crate generic_array; # extern crate typenum; # fn main() { let array = arr![u32; 1, 2, 3]; assert_eq!(array[2], 3); # } ``` 18699 41 %
