Typed error for format validation and decoding.

Every fallible public API in this crate returns FormatError; consumers can match on variants instead of parsing message strings (RELEASE_PLAN D2).

Decode(String)

Underlying MessagePack decode failure (truncated/corrupt input). Carries the codec’s message; the codec error type itself is not Clone.

Trait Implementations

impl Clone for FormatError

fn clone(&self) -> FormatError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Eq for FormatError

impl Error for FormatError

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<FormatError> for Error

fn from(source: FormatError) -> Self

Converts to this type from the input type.

impl PartialEq for FormatError

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