Function uniffi_build::generate_scaffolding

pub fn generate_scaffolding(udl_file: impl AsRef<Utf8Path>) -> Result<()>

Generate the rust “scaffolding” required to build a uniffi component.

Given the path to an UDL file, this function will call the uniffi-bindgen command-line tool to generate the pub extern "C" functions and other supporting code required to expose the defined interface from Rust. The expectation is that this will be called from a crate’s build script, and the resulting file will be include!()ed into the build.

This function will attempt to locate and parse a corresponding Cargo.toml to determine the crate name which will host this UDL.

Given an UDL file named example.udl, the generated scaffolding will be written into a file named example.uniffi.rs in the $OUT_DIR directory.
