Crate soothfast_macros 

Proc-macros for soothfast.

#[measured], #[bench], #[fixture], and #[mock_seam] register the annotated function into the soothfast registry (see soothfast-registry) without altering the function itself. #[measured]/#[bench] also accept checked performance claims: alloc = N, p99 = "1ms", and (bench only) complexity = "n log n" with setup_sized/sizes(...).

Attribute Macros

bench

Register a bench harness function, optionally fed by a setup fn.

fixture

Mark a deterministic input-builder. Registers metadata only; the function is referenced by name from #[bench(setup = ...)] / setup_sized.

measured

Register a zero-argument function as a directly measured item.

mock_seam

Mark a mock-backend setup fn, resolved at runtime by name via soothfast::mock::activate — referenced from a markdown mock=NAME / mock=NAME(ARG) tag, which is plain text rather than a syn::Path, so (unlike #[fixture], wired at compile time through a macro attribute argument) this can’t be called from a literal call site the macro controls; the registry stores a name-keyed fn pointer instead.

route

Declare the spec operation a handler implements — the code-side half of cargo soothfast spec check. Stackable for handlers serving several surfaces (REST + GraphQL + MCP).
