run_make_support/
lib.rs

1//! `run-make-support` is a support library for run-make tests. It provides command wrappers and
2//! convenience utility functions to help test writers reduce duplication. The support library
3//! notably is built via bootstrap cargo: this means that if your test wants some non-trivial
4//! utility, such as `object` or `wasmparser`, they can be re-exported and be made available through
5//! this library.
