Error type for Argon2 errors.

Variants

OutputTooShort

The output (hash) is too short (minimum is 4).

OutputTooLong

The output (hash) is too long (maximum is 2^32 - 1).

PwdTooShort

The password is too short (minimum is 0).

PwdTooLong

The password is too long (maximum is 2^32 - 1).

SaltTooShort

The salt is too short (minimum is 8).

SaltTooLong

The salt is too long (maximum is 2^32 - 1).

AdTooShort

The associated data is too short (minimum is 0).

AdTooLong

SecretTooShort

The secret value is too short (minimum is 0).

SecretTooLong

The secret value is too long (maximum is 2^32 - 1).

TimeTooSmall

The time cost (passes) is too small (minimum is 1).

TimeTooLarge

The time cost (passes) is too large (maximum is 2^32 - 1).

MemoryTooLittle

The memory cost is too small (minimum is 8 x parallelism).

MemoryTooMuch

The memory cost is too large (maximum 2GiB on 32-bit or 4TiB on 64-bit).

LanesTooFew

The number of lanes (parallelism) is too small (minimum is 1).

LanesTooMany

IncorrectType

Incorrect Argon2 variant.

IncorrectVersion

Incorrect Argon2 version.

DecodingFail

The decoding of the encoded data has failed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

impl From<DecodeError> for Error

fn from(_: DecodeError) -> Self

Performs the conversion.

impl PartialEq<Error> for Error

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl StructuralPartialEq for Error
