pub fn proto_path_to_axum(path: &str) -> StringExpand description
Convert a google.api.http path template to axum 0.8 path syntax.
The proto {param} form IS axum 0.8’s native capture syntax, so plain
single-segment params pass through verbatim. Only field-path templates and
bare wildcards need rewriting (axum 0.7 used :param; 0.8 uses {param}
and rejects any segment starting with :):
{name=*}(single segment) ->{name}{name=**}(multi-segment) ->{*name}(axum catch-all)- bare
*segment ->{wildcardN} - bare
**segment ->{*wildcardN}(axum catch-all)
