Struct Error 

pub struct Error { /* private fields */ }

A minimal representation of all possible errors that can occur.

Implementations

impl Error

pub fn end_of_file() -> Self

EOF while parsing.

pub fn invalid_type( unexpected: String, expected: String, pos: Option<usize>, ) -> Self

A mismatch occurred between the decoded and expected value types.

pub fn invalid_value( unexpected: String, expected: String, pos: Option<usize>, ) -> Self

The enclosed I/O error occurred while trying to read the encoded MessagePack data.

pub fn invalid_length( unexpected: String, expected: String, pos: Option<usize>, ) -> Self

A decoded sequence/map did not have the enclosed expected length.

pub fn unknown_length() -> Self

An encoded sequence/map did not provide a length.

pub fn number_out_of_range(pos: Option<usize>) -> Self

A numeric cast failed due to an out-of-range error.

pub fn uncategorized(msg: impl Display, pos: Option<usize>) -> Self

An otherwise uncategorized error occurred.

pub fn depth_limit_exceeded(pos: Option<usize>) -> Self

The depth limit was exceeded.

pub fn utf8(err: Utf8Error, pos: Option<usize>) -> Self

An encoded string could not be parsed as UTF-8.

pub fn reserved_type() -> Self

Reserved type.

pub fn io(err: Error) -> Self

A std::io::Error.

pub fn kind(&self) -> &ErrorKind

Returns the error’s kind.

pub fn pos(&self) -> Option<usize>

Returns the error’s position.

pub fn code(&self) -> ErrorCode

Returns the error’s code.

Trait Implementations

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 value using the given formatter.

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.
