Struct Error 

pub struct Error { /* private fields */ }

Crate-wide error type.

Implementations

impl Error

pub const fn not_recognized() -> Self

Creates a not-recognized error.

Returns

An Error wrapping RecognitionFailure::NotRecognized.

pub const fn unsupported_encoding() -> Self

Creates an unsupported-encoding error.

Returns

An Error wrapping RecognitionFailure::UnsupportedEncoding.

pub const fn truncated() -> Self

Creates a truncated-input error.

Returns

An Error wrapping RecognitionFailure::Truncated.

pub const fn malformed_container() -> Self

Creates a malformed-container error.

Returns

An Error wrapping RecognitionFailure::MalformedContainer.

pub const fn limit_exceeded() -> Self

Creates a limit-exceeded error.

Returns

An Error wrapping RecognitionFailure::LimitExceeded.

pub const fn crypto_mismatch() -> Self

Creates a crypto-mismatch error.

Returns

An Error wrapping RecognitionFailure::CryptoMismatch.

pub const fn compression_error() -> Self

Creates a decompression error.

Returns

An Error wrapping RecognitionFailure::CompressionError.

pub const fn token_error() -> Self

Creates a token-decoding error.

Returns

An Error wrapping RecognitionFailure::TokenError.

pub const fn recognition_failure(&self) -> Option<RecognitionFailure>

Returns the recognition failure when this error represents one.

Returns

Some with the wrapped RecognitionFailure; currently every Error carries one, so this never returns None.

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

Formats the error by delegating to its wrapped RecognitionFailure.

Arguments

• f - The formatter to write into.

Returns

A fmt::Result propagating any formatter write error.

impl Eq for Error

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 From<TokenError> for Error

fn from(_value: TokenError) -> Self

Converts a TokenError into the crate-level Error.

All token-parsing failures collapse into a single token error; the specific TokenError variant is not preserved.

Arguments

• _value - The TokenError to convert (its variant is discarded).

Returns

The crate Error produced by Error::token_error.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
