Struct Digest

pub struct Digest { /* private fields */ }

A parsed pair of algorithm:digest as defined by https://github.com/opencontainers/image-spec/blob/main/descriptor.md#digests

use std::str::FromStr;

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 AsRef<str> for Digest

fn as_ref(&self) -> &str

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

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 Hash for Digest

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 PartialEq for Digest

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

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 TryFrom<&str> for Digest

type Error = OciSpecError

The type returned in the event of a conversion error.

fn try_from(string: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for Digest

type Error = OciSpecError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Digest

impl StructuralPartialEq for Digest
