Implementations

impl Algorithm

pub fn key_length(&self) -> usize

Get the key length in bytes for this algorithm.

pub fn is_aes(&self) -> bool

Check if this is an AES algorithm.

pub fn is_rc4(&self) -> bool

Check if this is an RC4 algorithm.

Trait Implementations

impl Clone for Algorithm

fn clone(&self) -> Algorithm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Algorithm

impl Debug for Algorithm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Algorithm

impl PartialEq for Algorithm

fn eq(&self, other: &Algorithm) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
