Trait TryKeyInit 

pub trait TryKeyInit: KeySizeUser + Sized {
    // Required method
    fn new(key: &Key<Self>) -> Result<Self, InvalidKey>;

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

Types which can be fallibly initialized from a key.

Required Methods

fn new(key: &Key<Self>) -> Result<Self, InvalidKey>

Create new value from a fixed-size key.

Errors

• if the key is considered invalid according to rules specific to the implementing type

Provided Methods

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

Create new value from a variable size key.

Errors

• if the provided slice is the wrong length
• if the key is considered invalid by TryKeyInit::new

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.
