ic-build 0.3.1

//! Host-side artifact discovery, freshness, and Wasm build helpers.
//!
//! These functions keep integration-test artifacts in caller-selected target
//! directories and contain no application-specific package or profile policy.
//! Independent Wasm batches remain sequential; [`WasmBuildSession`] adds
//! explicit cross-call resolution reuse, while [`WasmBuildInputSnapshot`]
//! prepares a fixed specification set for concurrent readers. Both require a
//! caller-held source lease.
//!
//! Successful Wasm and generic artifact records retain their read-only exact
//! paths against cache replacement and pruning. Retain the record (or a clone)
//! through consumption; paths and artifact descriptors alone carry no ownership.
//! Batch reports own their successful records even when later entries fail.
//!
//! ```no_run
