Enum ssh_key::HashAlg

#[non_exhaustive]
pub enum HashAlg {
    Sha256,
    Sha512,
}

Hashing algorithms a.k.a. digest functions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sha256

SHA-256

Sha512

SHA-512

Implementations

impl HashAlg

pub fn new(id: &str) -> Result<Self>

pub fn digest(self, msg: &[u8]) -> Vec<u8>

Available on crate feature alloc only.

Compute a digest of the given message using this hash function.

Trait Implementations

impl AsRef<str> for HashAlg

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for HashAlg

fn clone(&self) -> HashAlg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HashAlg

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

Formats the value using the given formatter.

impl Default for HashAlg

fn default() -> Self

Returns the “default value” for a type.

impl Display for HashAlg

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

Formats the value using the given formatter.

impl FromStr for HashAlg

type Err = Error

The associated error which can be returned from parsing.

fn from_str(id: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for HashAlg

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Label for HashAlg

type Error = Error

Type returned in the event of an encoding error.

impl Ord for HashAlg

fn cmp(&self, other: &HashAlg) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<HashAlg> for HashAlg

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<HashAlg> for HashAlg

fn partial_cmp(&self, other: &HashAlg) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
