Enum RtpmapError 

#[non_exhaustive]
pub enum RtpmapError {
    MissingEncoding,
    MissingClockRate,
    ClockRate(String),
    EncodingParameter(String),
}

Why an a=rtpmap value names no format.

A value that names nothing is not an error the stack reports to anyone: both callers turn it into a non-match, which is the conservative reading of hostile input — a format sipx cannot identify is a format sipx does not agree to. The variants exist so the reason is available to a caller that wants to log it, and so a malformed clock rate is a typed outcome rather than a panic (AGENTS.md non-negotiable 3).

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.

MissingEncoding

Nothing before the first /.

MissingClockRate

No / at all. RFC 8866 §6.6 makes the clock rate part of the format’s identity, so a value without one identifies nothing.

ClockRate(String)

The clock rate is not a decimal number that fits in 32 bits.

EncodingParameter(String)

The encoding parameter is not a decimal number that fits in 32 bits. A value carrying more fields than the grammar has arrives here, because the extra / is not a digit.

Trait Implementations

impl Clone for RtpmapError

fn clone(&self) -> RtpmapError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RtpmapError

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

Formats the value using the given formatter.

impl Display for RtpmapError

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

Formats the value using the given formatter.

impl Error for RtpmapError

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 RtpmapError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
