pub enum Error {

        have: usize,

An RTCP packet parse / serialize error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BufferTooShort

Input (on parse) or output buffer (on serialize) shorter than required.

Fields

need: usize

Bytes required.

have: usize

Bytes available.

what: &'static str

What was being parsed/serialized.

OutputBufferTooSmall

Output buffer passed to serialize_into was smaller than serialized_len().

Fields

need: usize

Bytes required.

have: usize

Bytes available.

InvalidValue

A field value did not fit its wire bit-width, or the two’s-complement version field was not 2 (RFC 3550 §6.4.1: “The version defined by this specification is two (2)”), or a derived count (report/source count, item/reason length) overflowed its field, or SDES/BYE text was not valid UTF-8 (RFC 3550 §6.5: “encoded according to the UTF-8 encoding”).

Fields

field: &'static str

The offending field/derived-count name.

value: u64

The offending value.

reason: &'static str

Why it is invalid.

InvalidInput(&'static str)

A caller-supplied argument violated a documented precondition (e.g. an empty CompoundPacket or one not starting with SR/RR per RFC 3550 §6.1).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

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.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
