Struct BcryptHasher 

pub struct BcryptHasher { /* private fields */ }

A bcrypt password hasher that bundles its own cost parameters.

Implements PasswordHash so it can be used polymorphically with the crate’s verify_password function.

Design note — salt requirement

bcrypt requires exactly 16 bytes of salt. The PasswordHash::hash_password method writes raw hash bytes (23 bytes); for the full $2b$ string, use bcrypt_hash instead.

Implementations

impl BcryptHasher

pub fn new(params: BcryptParams) -> Self

Create a new hasher with explicit parameters.

pub fn with_cost(cost: u32) -> Result<Self, CryptoError>

Create a new hasher with the given cost factor.

Errors

Returns CryptoError::BadInput if cost is out of range [4, 31].

pub fn params(&self) -> &BcryptParams

Return a reference to the current parameters.

Trait Implementations

impl Clone for BcryptHasher

fn clone(&self) -> BcryptHasher

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BcryptHasher

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

Formats the value using the given formatter.

impl PasswordHash for BcryptHasher

fn name(&self) -> &'static str

Human-readable algorithm identifier (e.g. "Argon2id").

fn hash_password( &self, password: &[u8], salt: &[u8], _params: &dyn PasswordHashParams, out: &mut [u8], ) -> Result<(), CryptoError>

Hash password with salt using the given params; write output into out.
