static METHODS: OnceLock<Methods>Expand description
Resolved DefIds of std methods that are matched by generic name rather
than a fixed intrinsics! path (e.g. len, capacity, ::abs,
::checked_add, ::split_at, Iterator::position, …). Each group collects
every fn_def — from the std crates and the local crate (the
std-challenge suites re-implement Vec/slice-like types and their methods) —
whose name matches the group’s pattern. Callers match a call-site DefId
against these sets via contains.
