Struct argon2::ParamsBuilder

pub struct ParamsBuilder { /* private fields */ }

Builder for Argon2 Params.

Implementations

impl ParamsBuilder

pub const fn new() -> Self

Create a new builder with the default parameters.

pub fn m_cost(&mut self, m_cost: u32) -> &mut Self

Set memory size, expressed in kibibytes, between 8*p_cost and (2^32)-1.

pub fn t_cost(&mut self, t_cost: u32) -> &mut Self

Set number of iterations, between 1 and (2^32)-1.

pub fn p_cost(&mut self, p_cost: u32) -> &mut Self

Set degree of parallelism, between 1 and (2^24)-1.

pub fn keyid(&mut self, keyid: KeyId) -> &mut Self

Set key identifier.

pub fn data(&mut self, data: AssociatedData) -> &mut Self

Set associated data.

pub fn output_len(&mut self, len: usize) -> &mut Self

Set length of the output (in bytes).

pub const fn build(&self) -> Result<Params>

Get the finished Params.

This performs validations to ensure that the given parameters are valid and compatible with each other, and will return an error if they are not.

pub fn context( &self, algorithm: Algorithm, version: Version ) -> Result<Argon2<'_>>

Create a new Argon2 context using the provided algorithm/version.

pub const DEFAULT: ParamsBuilder = _

Default parameters (recommended).

Trait Implementations

impl Clone for ParamsBuilder

fn clone(&self) -> ParamsBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParamsBuilder

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

Formats the value using the given formatter.

impl Default for ParamsBuilder

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ParamsBuilder

fn eq(&self, other: &ParamsBuilder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<ParamsBuilder> for Params

type Error = Error

The type returned in the event of a conversion error.

fn try_from(builder: ParamsBuilder) -> Result<Params>

Performs the conversion.
