Enum Error 

#[non_exhaustive]
pub enum Error {
    Algorithm,
    Crypto,
    EncodingInvalid,
    OutOfMemory,
    OutputSize,
    ParamInvalid {
        name: &'static str,
    },
    ParamsInvalid,
    PasswordInvalid,
    SaltInvalid,
    Version,
}

Password hashing errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Algorithm

Unsupported algorithm.

Crypto

Cryptographic error.

EncodingInvalid

Encoding errors (e.g. Base64).

OutOfMemory

Out of memory (heap allocation failure).

OutputSize

Output size invalid.

ParamInvalid

Invalid named parameter.

Fields

name: &'static str

Parameter name.

ParamsInvalid

Invalid parameters.

PasswordInvalid

Invalid password.

SaltInvalid

Invalid salt.

Version

Invalid algorithm version.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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<(), Error>

Formats the value using the given formatter.

impl Error for Error

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for Error

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

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
