Struct Hash 

pub struct Hash { /* private fields */ }

Contains the Argon2 hash in PHC format.

The hash can be safely stored in your database without special security measures since it’s already cryptographically hashed. However, avoid unnecessary cloning or logging to minimize exposure.

PHC Format

The hash is stored in PHC (Password Hashing Competition) format which includes:

• Algorithm identifier (argon2id)
• Version
• Parameters (memory cost, time cost, parallelism)
• Salt (base64-encoded, embedded in the hash string)
• Hash output (base64-encoded)

Example: $argon2id$v=19$m=19456,t=2,p=1$<salt>$<hash>

The salt is embedded within the PHC string and can be extracted if needed using the password_hash crate’s PasswordHash::new() method.

The hash can be accessed using the auto-generated getter method hash() provided by the Getters derive macro.

Implementations

impl Hash

Auto-generated by derive_getters::Getters.

pub fn hash(&self) -> &String

Get field hash from instance of Hash.

Trait Implementations

impl Debug for Hash

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

Formats the value using the given formatter.

impl PartialEq for Hash

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