Trait KeyInit 

pub trait KeyInit: Sized + KeySizeUser {
    // Required method
    fn new(key: &GenericArray<u8, Self::KeySize>) -> Self;

    // Provided method
    fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength> { ... }
}

Types which can be initialized from key.

Required Methods

fn new(key: &GenericArray<u8, Self::KeySize>) -> Self

Create new value from fixed size key.

Provided Methods

fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength>

Create new value from variable size key.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
