Struct PasswordHashWorkFactor 

pub struct PasswordHashWorkFactor { /* private fields */ }

Argon2id work factor used when creating new password hashes.

Implementations

impl PasswordHashWorkFactor

pub const fn rfc_9106_second_recommended() -> Self

Returns the RFC 9106 second recommended Argon2id profile.

This uses 64 MiB of memory, three iterations, four lanes, and a 32-byte output.

pub fn new( memory_kib: u32, iterations: u32, parallelism: u32, output_length: usize, ) -> Result<Self>

Creates a custom Argon2id work factor.

Errors

Returns an error when the output length or Argon2 cost parameters fall outside the ranges accepted by the Argon2 implementation.

pub const fn memory_kib(self) -> u32

Memory cost in KiB.

pub const fn iterations(self) -> u32

Number of Argon2 passes.

pub const fn parallelism(self) -> u32

Number of Argon2 lanes.

pub const fn output_length(self) -> usize

Password-hash output length in bytes.

Trait Implementations

impl Clone for PasswordHashWorkFactor

fn clone(&self) -> PasswordHashWorkFactor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PasswordHashWorkFactor

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

Formats the value using the given formatter.

impl Default for PasswordHashWorkFactor

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PasswordHashWorkFactor

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