lib.rs

1//! Canonical embedded Harn standard library source catalog.
2//!
3//! This crate intentionally contains only static source strings so runtime and
4//! static tooling crates can share the same stdlib modules without depending on
5//! each other. Loading this catalog is pure: modules cannot register ambient
6//! effects, and every effectful stdlib function must receive its typed Harness
7//! capability explicitly from the caller, including callbacks that may perform
8//! effects.
