Struct minicbor::decode::Error

pub struct Error { /* private fields */ }

Decoding error.

Implementations

impl Error

pub fn end_of_input() -> Self

The end of the input bytes has been reached.

pub fn type_mismatch(ty: Type) -> Self

A type error.

pub fn message<T: Display>(msg: T) -> Self

Construct an error with a generic message.

With feature "alloc" any type T: Display is accepted which allows formatted strings. Otherwise only a &'static str can be used as a message.

pub fn custom<T: Error + Send + Sync + 'static>(err: T) -> Self

A custom error.

Requires feature "std".

pub fn at(self, pos: usize) -> Self

Set the decoding position where the error happened.

pub fn with_message<T: Display>(self, msg: T) -> Self

Add a message to this error value.

With feature "alloc" any type T: Display is accepted which allows formatted strings. Otherwise only a &'static str can be used as a message.

pub fn is_end_of_input(&self) -> bool

pub fn is_type_mismatch(&self) -> bool

pub fn is_message(&self) -> bool

pub fn is_custom(&self) -> bool

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
