Module libraries 

Embedded R7RS standard library source registry.

Each entry maps a library name (e.g. &["scheme", "base"]) to the embedded Scheme source for its define-library form. These are loaded on-demand by the evaluator when a library is first imported.

Feature-gated library inclusion

Each library is gated behind a corresponding Cargo feature flag. By default, the all-libraries feature enables every library, preserving backward compatibility. For resource-constrained embedded targets, disable default features and select only the libraries you need:

[dependencies.grift_core]
version = "..."
default-features = false
features = ["scheme-base", "scheme-write"]

Available feature flags
