Struct TransitionPlan 

pub struct TransitionPlan {
    pub at_pts: u64,
    pub pts_rebase_offset: i128,
    pub discontinuity: bool,
}

The computed plan for joining from into to at Self::at_pts.

Fields

at_pts: u64

The channel-timeline instant the join happens at — to’s planned_start.

pts_rebase_offset: i128

Add this to one of to’s own PTS values to place it on the shared channel timeline (see Self::rebase). i128 so it can hold the full possible difference of two u64 instants without clamping — this crate never silently narrows a rebase computation. May be negative when to’s own clock numbering starts after the channel instant it is joining at (an unusual but not-impossible schedule).

discontinuity: bool

Whether from and to carry different CodecConfigIds — a discontinuity that must be signalled downstream (init-segment change / new codec config), never something this crate transcodes or conforms away.

Implementations

impl TransitionPlan

pub fn plan(from: &ScheduleEntry, to: &ScheduleEntry) -> Self

Plan the transition from from into to. to.planned_start is the channel-timeline instant the join happens at; the rebase offset is derived so that to.source_start_pts, once rebased, lands exactly on that instant.

pub fn rebase(&self, source_pts: u64) -> Option<u64>

Map one of to’s own PTS values onto the shared channel timeline (source_pts + pts_rebase_offset).

Returns None rather than wrapping if the rebased instant would fall outside u64’s range (e.g. a source PTS before the source’s own declared start, rebasing to before the join instant) — this crate never silently produces a timeline instant that doesn’t correspond to the input.
