Struct DecodeError 

pub struct DecodeError { /* private fields */ }

Why bytes are not a module, and where.

Examples

use bytecode_lang::{decode, DecodeErrorKind};

let err = decode(b"LSB\0\x09\0\0\0\0\0\0\0").unwrap_err();
assert_eq!(err.kind(), &DecodeErrorKind::UnsupportedVersion(9));
assert_eq!(err.offset(), 4);
assert_eq!(
    err.to_string(),
    "at byte 4: unsupported format version 9 (this decoder reads version 2)",
);

Implementations

impl DecodeError

pub fn offset(&self) -> usize

The byte offset in the input where the problem was found.

Examples

use bytecode_lang::decode;

assert_eq!(decode(b"").unwrap_err().offset(), 0);

pub fn kind(&self) -> &DecodeErrorKind

What the problem is.

Examples

use bytecode_lang::{decode, DecodeErrorKind};

assert_eq!(decode(b"").unwrap_err().kind(), &DecodeErrorKind::UnexpectedEnd);

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecodeError

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

impl Eq for DecodeError

impl Error for DecodeError

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 PartialEq for DecodeError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
