Implementations

impl Digest

pub fn algorithm(&self) -> &DigestAlgorithm

The algorithm name (e.g. sha256, sha512)

pub fn digest(&self) -> &str

The algorithm digest component. When this is one of the SHA family (SHA-256, SHA-384, etc.) the digest value is guaranteed to be a valid length with only lowercase hexadecimal characters. For example with SHA-256, the length is 64.

Trait Implementations

impl Clone for Digest

fn clone(&self) -> Digest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Digest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Digest

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Digest

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

Formats the value using the given formatter.

impl From<Sha256Digest> for Digest

fn from(value: Sha256Digest) -> Self

Converts to this type from the input type.

impl FromStr for Digest

type Err = OciSpecError

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 PartialEq for Digest

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

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

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 Serialize for Digest

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Digest

impl StructuralPartialEq for Digest
