A recoverable oddity recorded during SDP parsing rather than failed on.

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.

UnparseableNumericAttribute

A numeric SDP attribute could not be parsed as a positive integer.

FreeSWITCH’s atoi accepts "abc" as 0 and treats 0 as “not set”. A strict parser records this as a warning rather than hard-failing so the session is not dropped over a cosmetic attribute.

Fields

attribute: String

The attribute name, e.g. "ptime" or "maxptime".

raw_value: String

The raw on-wire value that could not be parsed.

CodecStringQualifier

A codec-string qualifier value was skipped during lenient parsing.

Produced by CodecString::parse_lenient when a qualifier overflows u32 or carries no recognised letter. The qualifier is omitted from the parsed entry. In strict mode (FromStr) the same condition is a hard error.

Fields

raw: String

The raw qualifier part that could not be parsed (e.g. "9999999999h").

reason: String

Why parsing failed.

FmtpUnrepresentable

A codec’s fmtp could not be embedded in the codec-string entry and was cleared.

Occurs when the offer’s a=fmtp value contains characters that are unrepresentable in the codec-string format (e.g. a dotted fmtp like br=13.2-24.4 against a bare policy entry that has no module prefix). The codec entry is still emitted; only the fmtp qualifier is absent. The original fmtp is preserved here for inspection.

Fields

codec_name: String

The codec name for which fmtp could not be embedded.

fmtp: String

The fmtp value that could not be represented.

reason: String

Human-readable reason the fmtp could not be embedded.

CodecNameUnrepresentable

An offered codec’s a=rtpmap encoding name cannot be represented as a codec-string entry at all, and the codec was skipped.

Occurs when the name itself contains a codec-string grammar delimiter (, @ ~ . ' \ or ASCII whitespace). Unlike FmtpUnrepresentable, there is no entry to fall back to — the whole codec is dropped, narrowing the emitted list. Distinct from UnmappedPayload: that payload type had no rtpmap name whatsoever, whereas this one has a name that simply cannot survive the codec-string grammar.

Fields

codec_name: String

The raw, unrepresentable encoding name from a=rtpmap.

reason: String

Human-readable reason the name could not be embedded.

MalformedMediaSection

A single m= section was structurally broken and was skipped entirely.

Occurs when an a=rtpmap, a=fmtp, or m= format-list entry in one media section cannot be parsed at all (as opposed to CodecNameUnrepresentable, which drops a single codec). Every other section’s codecs are still parsed and returned.

Fields

media_type: String

The media type of the skipped section (e.g. "audio").

reason: String

Human-readable reason the section could not be parsed.

CodecStringTruncated

A lenient parse read more comma-separated slots than FreeSWITCH would.

Every entry parsed is returned; the switch itself keeps only the first limit slots (switch_types.h:595), empty ones included, and loses the rest with no log.

Fields

entries: usize

How many comma-separated slots the input carried.

limit: usize

The cap, CodecString::MAX_SWITCH_ENTRIES.

NonCanonicalDirectionAttribute

A value-less attribute names a direction in a case RFC 8866 does not accept.

It is not read as one, so the section keeps the direction of the level above it — which is what the peer wrote only by coincidence.

Fields

attribute: String

The attribute name as the peer spelled it.
