Enum ChannelState 

#[non_exhaustive]
#[repr(u8)]
pub enum ChannelState {
    CsNew = 0,
    CsInit = 1,
    CsRouting = 2,
    CsSoftExecute = 3,
    CsExecute = 4,
    CsExchangeMedia = 5,
    CsPark = 6,

    CsHangup = 10,

    CsNone = 13,
}

Channel state from switch_channel_state_t – carried in the Channel-State header as a string (CS_ROUTING) and in Channel-State-Number as an integer.

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.

CsNew = 0

CsInit = 1

CsRouting = 2

CsSoftExecute = 3

CsExecute = 4

CsExchangeMedia = 5

CsPark = 6

CsConsumeMedia = 7

CsHibernate = 8

Implementations

impl ChannelState

pub const fn as_str(&self) -> &'static str

Canonical wire-format string.

impl ChannelState

pub fn from_number(n: u8) -> Option<ChannelState>

Parse from the Channel-State-Number integer header value.

pub fn as_number(&self) -> u8

Integer discriminant matching switch_channel_state_t.

pub fn is_terminal(&self) -> bool

Whether the channel is gone: CS_DESTROY, and nothing else.

The session’s run loop exits on CS_DESTROY; CS_NONE is a running_state sentinel the state machine aborts on if it ever reaches it, so it ends nothing despite sorting above CS_DESTROY.

CHANNEL_STATE events carry no variable_* headers, so end-of-life detected here cannot be paired with any channel variable from the same event. The variable-bearing terminal event is CHANNEL_HANGUP_COMPLETE, which is also where variable_hangup_cause first appears – CHANNEL_HANGUP carries only the Hangup-Cause header.
