pub(crate) const PARAM_FILLER_MARKER: &str = ".__MX_PARAM_FILLER__ ";Expand description
Prefix of a generated @param line in a standalone function’s wrapper
(#' .__MX_PARAM_FILLER__ @param x (no documentation available)), for the
wrapper registry to resolve when it writes the file
(resolve_standalone_pages in miniextendr-api/src/registry.rs, which
spells the same prefix). Whether an author @rdname topic names the
function’s own page or its file’s stem page (the opt-in group page,
#1289), and whether another function on the page documents the argument,
is only known then. The registry keeps the line (without the prefix) when
the function stays on its own or file-stem page and no other function
there documents the argument, and drops it otherwise. roxygen2 keeps the later of two @param lines for one name, so
a filler written after the real description would replace it.
