Struct ParseCodecOptionError 

pub struct ParseCodecOptionError { /* private fields */ }

Error returned when a textual codec option is unsupported.

The original input is retained verbatim for diagnostics. Use Self::kind and Self::accepted_spellings for programmatic recovery. Serde errors remain Serde errors; this type is the FromStr contract only.

Implementations

impl ParseCodecOptionError

pub const fn kind(&self) -> CodecOptionKind

Return the option family that rejected the input.

pub fn input(&self) -> &str

Return the original, unnormalized input.

pub const fn accepted_spellings(&self) -> &'static [&'static str]

Return every spelling accepted by the rejected option family.

impl Error for ParseCodecOptionError

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
