Struct DigestAlgorithm

pub struct DigestAlgorithm(/* private fields */);

Delegation signer digest algorithm numbers.

These numbers are used in the DS resource record to specify how the key digest in the record has been generated.

For the currently registered values see the IANA registration. This type is complete as of the registry update of 2012-04-13.

Implementations

impl DigestAlgorithm

pub const SHA1: DigestAlgorithm

Specifies that the SHA-1 hash function is used.

Implementation of this function is currently mandatory.

pub const SHA256: DigestAlgorithm

Specifies that the SHA-256 hash function is used.

Implementation of this function is currently mandatory.

pub const GOST: DigestAlgorithm

Specifies that the GOST R 34.11-94 hash function is used.

Use of this hash function is described in RFC 5933. Implementing the function is optional.

pub const SHA384: DigestAlgorithm

Specifies that the SHA-384 hash function is used.

Use of this hash function is described in RFC 6605. Implementing the function is optional.

impl DigestAlgorithm

pub const COMPOSE_LEN: u16 = 1u16

pub const fn from_int(value: u8) -> Self

Returns a value from its raw integer value.

pub const fn to_int(self) -> u8

Returns the raw integer value for a value.

Formats the value using the given formatter.

impl Display for DigestAlgorithm

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

Formats the value using the given formatter.

impl<'a> From<&'a DigestAlgorithm> for u8

fn from(value: &'a DigestAlgorithm) -> Self

Converts to this type from the input type.

impl FromStr for DigestAlgorithm

type Err = ParseIntError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for DigestAlgorithm

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,

impl Ord for DigestAlgorithm

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

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

Tests greater than (for self and other) and is used by the > operator.

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