Enum TranscodeDecodeError 

pub enum TranscodeDecodeError<E> {
    Failure(TranscodeFailure),
    Domain(TranscodeDomainError<E>),
}

Error reported by a decode-oriented transcode operation.

Variants

Failure(TranscodeFailure)

Framework-level transcode failure.

Domain(TranscodeDomainError<E>)

Domain-specific codec, charset, or policy error.

Implementations

impl<E> TranscodeDecodeError<E>

pub const fn domain_reset(source: E) -> Self

Creates a reset-phase domain-specific transcode error.

pub const fn domain_main(source: E, input_index: usize) -> Self

Creates a main-phase domain-specific transcode error.

pub const fn domain_main_with_consumed( source: E, input_index: usize, input_consumed: Option<NonZeroUsize>, ) -> Self

Creates a main-phase domain-specific transcode error with decode consumption context.

pub const fn domain_finish(source: E) -> Self

Creates a finish-phase domain-specific transcode error.

pub fn from_decode_failure( failure: DecodeFailure<E>, input_index: usize, available: usize, ) -> Self

Converts a low-level decode failure into a decode transcode error.

pub const fn is_domain(&self) -> bool

Returns whether this error wraps a domain error.

pub const fn failure_ref(&self) -> Option<&TranscodeFailure>

Returns the framework failure carried by this error.

pub const fn domain_error_ref(&self) -> Option<&TranscodeDomainError<E>>

Borrows the wrapped domain error and transcode context.

pub const fn domain_ref(&self) -> Option<&E>

Borrows the wrapped domain error.

pub fn map_domain<F, T>(self, f: F) -> TranscodeDecodeError<T>

where F: FnOnce(E) -> T,

Maps the wrapped domain error while preserving framework failures.

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
