Enum Block 

#[non_exhaustive]
pub enum Block {
    ChannelData {
        fields: Vec<(String, String)>,
        variables: Vec<(String, String)>,
    },
    Sdp {
        direction: SdpDirection,
        body: Vec<String>,
    },
    CodecNegotiation {
        media: CodecMedia,
        comparisons: Vec<(CodecOffer, CodecOffer)>,
        matched: Vec<CodecOffer>,
        near_matched: Vec<CodecOffer>,
    },
}

Structured data extracted from a multi-line dump that follows a primary log entry.

Each variant corresponds to a block type that the stream state machine recognizes and reassembles from continuation lines.

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.

ChannelData

Channel variable dump — Channel-* fields and variable_* key-value pairs. Multi-line variable values (e.g. embedded SDP) are reassembled with \n separators.

Fields

fields: Vec<(String, String)>

variables: Vec<(String, String)>

Sdp

SDP session description body, collected line by line.

Fields

direction: SdpDirection

body: Vec<String>

CodecNegotiation

Codec negotiation sequence for one media type. A run only ever covers a single CodecMedia; audio and video traces never share a block.

Fields

media: CodecMedia

comparisons: Vec<(CodecOffer, CodecOffer)>

(remote offer, local implementation) for each pair compared.

matched: Vec<CodecOffer>

near_matched: Vec<CodecOffer>

Codecs kept as fallbacks because only their ptime differed.

Implementations

impl Block

pub fn field(&self, name: &str) -> Option<&str>

Value of a Channel-* field in a CHANNEL_DATA dump, or None if this block is another kind or never carried that field.

pub fn variable<V: VariableName>(&self, var: V) -> Option<&str>

Value of a channel variable in a CHANNEL_DATA dump.

Accepts any of freeswitch-types’ variable-name enums, and spares the caller from knowing that a dump spells its keys with the variable_ prefix that SessionState::variable strips — the two surfaces answer the same question the same way.

impl Block

pub fn sdp_codecs(&self) -> Option<Result<SdpCodecs, SdpCodecError>>

Codecs described by an SDP body.

None when there is no body to read — another block type, or an SDP marker that carried none. Sofia logs several (Duplicate SDP, Processing updated SDP) purely as announcements, and an empty body is absence rather than a malformed session.

Parsed on each call rather than stored — see docs/design-rationale.md. Only a session-level failure is an Err: a malformed a=rtpmap or a broken media section degrades into SdpCodecs::warnings.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block
