Enum Interlace 

pub enum Interlace {
    Any,
    Progressive,
    Interleaved,
}

Scan structure of raw video (M935). Any is the unconstrained default nearly every caps site uses, and it reads as “progressive unless declared” (GStreamer’s meaning for an absent interlace-mode): a decoder that sees interlaced pictures refines it to Interleaved via CapsChanged, which is what deinterlace mode=auto acts on. Unlike Dim::Any / Rate::Any the wildcard survives fixate and counts as fixed, so the field never blocks a solve and pre-M935 negotiations are unchanged.

Variants

Any

Progressive

Interleaved

Both fields woven into one frame, top field first (ffmpeg’s default for a stream that declares no field order).

Implementations

impl Interlace

pub fn intersect(&self, other: &Interlace) -> Option<Interlace>

Intersect two scan constraints: Any is the identity, equal values pass, Progressive vs Interleaved is an empty overlap.
