Enum DecodeError 

pub enum DecodeError {
    Truncated,
    MissingParameterSet,
    Unsupported(&'static str),
    Internal(&'static str),
}

Decode errors.

Variants

Truncated

Bitstream ended unexpectedly.

MissingParameterSet

A required parameter set was missing before a slice.

Unsupported(&'static str)

A coding tool outside the implemented subset appeared in the stream.

Internal(&'static str)

A DECODER invariant did not hold – a helper thread died, a pooled buffer was missing, a picture was not where the state machine expected it. The stream is not necessarily at fault.

This variant exists so those conditions can be REPORTED rather than panicked. A decoder eats attacker-controlled bytes, so an unwind is a denial-of-service primitive; a Result the caller can handle is not. Every site that once carried an .expect() on an internal invariant returns this instead.

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 Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

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 From<OutOfData> for DecodeError

fn from(_: OutOfData) -> Self

Converts to this type from the input type.

impl PartialEq for DecodeError

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

Equality operator ==.

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

Inequality operator !=.
