Enum ContinuityEvent 

pub enum ContinuityEvent {
    Continuous,
    Duplicate,
    NoPayload,
    Dropped {
        gap: u8,
    },
    Discontinuity,
}

Outcome of feeding one packet to a ContinuityTracker.

Variants

Continuous

CC differs from previous by exactly 1 mod 16 (or this is the first packet) — the expected case.

Duplicate

CC matched the previous packet’s value. §2.4.3.3: “duplicate packets may be sent as two, and only two, consecutive TS packets”. The current packet may be discarded if the previous one was already emitted.

NoPayload

CC did not increment (adaptation_field_control was '00' or '10'). Spec-permitted; not a drop.

Dropped

CC jumped by more than 1 — at least one packet was lost. Reported delta is (current - previous - 1) mod 16, i.e. the minimum number of packets we know are missing (the counter is only 4 bits so larger losses are indistinguishable).

Fields

gap: u8

Discontinuity

discontinuity_indicator = 1 on this packet — §2.4.3.4 says the CC may be discontinuous and we should not interpret the gap as a drop.

Trait Implementations

impl Clone for ContinuityEvent

fn clone(&self) -> ContinuityEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ContinuityEvent

impl Debug for ContinuityEvent

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

Formats the value using the given formatter.

impl Eq for ContinuityEvent

impl PartialEq for ContinuityEvent

fn eq(&self, other: &ContinuityEvent) -> 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.
