Package cm contains helper types and functions used by generated packages, such as option<t>, result<ok, err>, variant, list, and resource. These are intended for use by generated Component Model bindings, where the caller converts to a Go equivalent. It attempts to map WIT semantics to their equivalent in Go where possible.
Package cm and generated bindings from wit-bindgen-go may have compatibility issues with the Go garbage collector, as they directly represent variant and result types as tagged unions where a pointer shape may be occupied by a non-pointer value. The GC may detect and throw an error if it detects a non-pointer value in an area it expects to see a pointer. This is an area of active development.
