[][src]Enum gstreamer::CapsIntersectMode

#[non_exhaustive]pub enum CapsIntersectMode {
    // some variants omitted

Modes of caps intersection

CapsIntersectMode::ZigZag tries to preserve overall order of both caps by iterating on the caps' structures as the following matrix shows:

      | 1  2  4  7
caps2 | 3  5  8 10
      | 6  9 11 12

Used when there is no explicit precedence of one caps over the other. e.g. tee's sink pad getcaps function, it will probe its src pad peers' for their caps and intersect them with this mode.

CapsIntersectMode::First is useful when an element wants to preserve another element's caps priority order when intersecting with its own caps. Example: If caps1 is [A, B, C] and caps2 is [E, B, D, A], the result would be [A, B], maintaining the first caps priority on the intersection.

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.

Zig-zags over both caps.


Keeps the first caps order.
