Enum HashAlgorithm 

#[repr(u64)]
pub enum HashAlgorithm {
    Sha1 = 1,
    Sha256 = 2,
    Sha512 = 64,
}

A hash algorithm selected at run time, as named in DKIM tags (the hash part of a=, and the h= tag of DKIM key records) and in the h= tag of DKIM2 Message-Instance header fields.

Variants

Sha1 = 1

SHA-1 (sha1).

Sha256 = 2

SHA-256 (sha256).

Sha512 = 64

SHA-512 (sha512). Used by DKIM2 only.

Implementations

impl HashAlgorithm

pub fn hash(&self, data: impl Writable) -> HashOutput

Hashes the bytes written by data with this algorithm.

impl HashAlgorithm

pub fn parse(name: &str) -> Option<Self>

Parses a DKIM hash algorithm name (sha1 or sha256), ignoring ASCII case. Returns None for any other name, including sha512, which DKIM does not define.

pub fn name(&self) -> &'static str

Returns the lowercase algorithm name (sha1, sha256 or sha512).

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HashAlgorithm

impl Debug for HashAlgorithm

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

Formats the value using the given formatter.
