pub fn parse_specs(
v: Option<&Value>,
) -> (Option<(GutterKind, String)>, Option<(GutterKind, String)>)Expand description
Parse an op’s gutter: param value into its (during, final)
template forms. Shared by the wrapper-cascade arm (which builds
the GutterDispenser and stores the specs on the activity) and
the poll wrapper (which re-publishes the during form per poll
iteration so a single long drain op keeps a live cell).
