Struct 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 tag_mismatch(tg: Tag) -> Self

A tag error.

pub fn message(msg: &'static str) -> 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 at(self, pos: usize) -> Self

Set the decoding position where the error happened.

pub fn with_message(self, msg: &'static str) -> 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_tag_mismatch(&self) -> bool

pub fn is_message(&self) -> bool

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

Byte index of the input at which the error occurred.

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
