Enum HashAlgorithm 

pub enum HashAlgorithm {
    Sha256,
    Sha384,
    Sha512,
}

Supported cryptographic hash algorithms

All algorithms use the SHA-2 family for security and performance.

Variants

Sha256

SHA-256 (256-bit/32-byte output)

Sha384

SHA-384 (384-bit/48-byte output) - Default

Sha512

SHA-512 (512-bit/64-byte output)

Implementations

impl HashAlgorithm

pub fn as_str(&self) -> &'static str

Get algorithm name as string

Example

use atlas_common::hash::HashAlgorithm;

assert_eq!(HashAlgorithm::Sha256.as_str(), "sha256");

pub fn output_size(&self) -> usize

Get the output size in bytes

Example

use atlas_common::hash::HashAlgorithm;

assert_eq!(HashAlgorithm::Sha256.output_size(), 32);
assert_eq!(HashAlgorithm::Sha512.output_size(), 64);

pub fn hex_length(&self) -> usize

Get the output size in hex characters

Example

use atlas_common::hash::HashAlgorithm;

assert_eq!(HashAlgorithm::Sha256.hex_length(), 64);

pub fn validate_hash(&self, hash: &str) -> bool

Check if a hash string matches this algorithm’s expected format

Example

use atlas_common::hash::HashAlgorithm;

let hash = "a".repeat(64);
assert!(HashAlgorithm::Sha256.validate_hash(&hash));
assert!(!HashAlgorithm::Sha384.validate_hash(&hash));

Trait Implementations

impl Clone for HashAlgorithm

fn clone(&self) -> HashAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HashAlgorithm

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

Formats the value using the given formatter.

impl Default for HashAlgorithm

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HashAlgorithm

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HashAlgorithm

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

Formats the value using the given formatter.

impl FromStr for HashAlgorithm

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

Parse algorithm from string

Accepts: “sha256”, “sha-256”, “sha384”, “sha-384”, “sha512”, “sha-512” (case-insensitive)

type Err = Error

The associated error which can be returned from parsing.

impl PartialEq for HashAlgorithm

fn eq(&self, other: &HashAlgorithm) -> 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 HashAlgorithm

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for HashAlgorithm

impl Eq for HashAlgorithm

impl StructuralPartialEq for HashAlgorithm
