Rust API reference

The Rust API provides contract parsing, compilation, evaluation, and export. Structs expose data through fields; constructors and methods are listed with their types. Free functions are documented under the module that contains them.

Reference	What it covers
Compiler: parcel-core	ContractDoc, Registry, type checking, compilation and diagnostics.
Runtime: parcel-runtime	Caller, validation, caller decisions, shape rules and differential testing.
Artifacts and exports	Compiled bytes, function pins, SQL and Substrait export, WebAssembly loading.
WebAssembly functions	Writing and verifying a custom function with parcel-udf.

parcel-core parses and compiles contracts. parcel-runtime evaluates the compiled results and provides export and loading functions.
