Error returned by codec operations.

Variants

MissingPrefix

A configured prefix was required but missing.

Fields

prefix: String

Required prefix.

InvalidDigit

Input contained a digit that is invalid for the requested radix.

Fields

radix: u32

Numeric radix expected by the codec.

index: usize

Character byte index in the original input.

character: char

Invalid character.

InvalidLength

Input length does not satisfy a codec requirement.

Fields

context: &'static str

Human-readable input part whose length was invalid.

expected: String

Human-readable length requirement.

actual: usize

Actual length observed by the codec.

InvalidEscape

Input contained a malformed or unsupported escape sequence.

Fields

index: usize

Byte index of the escape marker in the original input.

escape: String

Escape sequence fragment that caused the error.

reason: String

Human-readable reason the escape was rejected.

InvalidCharacter

Input contained a character that cannot appear in that context.

Fields

index: usize

Character byte index in the original input.

character: char

Invalid character.

reason: String

Human-readable reason the character was rejected.

InvalidInput

Input was rejected by a codec-specific validator.

Fields

codec: &'static str

Stable codec name, such as base64.

reason: String

Human-readable reason reported by the codec.

InvalidUtf8

Decoded bytes were not valid UTF-8.

Fields

source: FromUtf8Error

Underlying UTF-8 conversion error.

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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<FromUtf8Error> for CodecError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
