Struct Digest 

pub struct Digest { /* private fields */ }

A content-addressable digest in the format algorithm:hex.

Currently only SHA256 is supported as per OCI specification.

Implementations

impl Digest

pub fn new(algorithm: Algorithm, hex: impl Into<String>) -> Result<Self, Error>

Creates a new digest from algorithm and hex string.

The hex string is normalized to lowercase per OCI specification.

pub fn sha256(data: &[u8]) -> Self

Computes the SHA256 digest of the given data.

pub fn sha384(data: &[u8]) -> Self

Computes the SHA384 digest of the given data.

pub fn sha512(data: &[u8]) -> Self

Computes the SHA512 digest of the given data.

pub fn compute(algorithm: Algorithm, data: &[u8]) -> Self

Computes a digest using the requested algorithm.

pub fn algorithm(&self) -> Algorithm

Returns the algorithm component.

pub fn hex(&self) -> &str

Returns the hex component.

Trait Implementations

impl Clone for Digest

fn clone(&self) -> Digest

Returns a duplicate 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 FromStr for Digest

type Err = Error

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.
