Struct ChainLink 

pub struct ChainLink {
    pub index: usize,
    pub output: Caps,
}

One element on an auto-plugged chain: which registered ElementDesc it is (index into the searched slice) and the output caps the search chose for it (the source-pad alternative it was matched to produce). The caps pin the media type and format the element must emit, which a format-flexible element (a converter, a multi-format decoder) needs to be constructed; geometry and framerate may still be open and fixate later at instance negotiation.

Fields

index: usize

Index into the descs slice passed to find_chain.

output: Caps

The caps this element was chosen to produce on its source pad.
