pub fn parse_with(
v: &Value,
refs: Option<&mut NameRefs<'_>>,
) -> Result<Vec<Keyframe>, String>Expand description
parse with a token lookup: a $name in a stop’s width,
height, bg or radius resolves through refs, and one that
misses leaves that slot unnamed and is remembered on the refs for the
binding to raise. Without refs a $name is an error, since there is
nothing to resolve it against.
