Macro schema_from_file 

macro_rules! schema_from_file {
    ($path:expr) => { ... };
}

Helper macro to embed a schema.cdm file and export it via the WASM _schema() function.

This is a Rust-specific convenience for plugin development. It uses include_str!() to embed the schema file at compile time, making the WASM binary self-contained.

Example

use cdm_plugin_api::schema_from_file;

// Embeds ../schema.cdm and creates the _schema() export
schema_from_file!("../schema.cdm");

How it works

The macro expands to:

• Load the file contents at compile time using include_str!()
• Create a function that returns the embedded schema string
• Use the export_schema! macro to wrap it with proper FFI handling

Note

This is optional - plugins can implement _schema() however they want. This macro is just a convenience for Rust plugins that want to keep their schema in a separate .cdm file.
