Struct ExpandOptions 

pub struct ExpandOptions {
    pub keep_decorators: Option<bool>,
    pub external_decorator_modules: Option<Vec<String>>,
    pub config_path: Option<String>,
}

Options for macro expansion.

Used by expand_sync to configure expansion behavior.

Fields

keep_decorators: Option<bool>

If true, preserves @derive decorators in the output. If false (default), decorators are stripped after expansion.

external_decorator_modules: Option<Vec<String>>

Additional decorator module names from external macros.

These are used during decorator stripping to identify Macroforge-specific decorators that should be removed from the output. Built-in decorator modules (like “serde”, “debug”) are automatically included.

External macro packages should export their decorator module names, which plugins can collect and pass here.

Example

expandSync(code, filepath, {
  keepDecorators: false,
  externalDecoratorModules: ["myMacro", "customValidator"]
});

config_path: Option<String>

Path to a previously loaded config file.

When provided, the expansion will use the cached configuration (including foreign types) from this path. The config must have been previously loaded via load_config.

Example

// First, load the config
const configResult = loadConfig(configContent, configPath);

// Then use it during expansion
expandSync(code, filepath, { configPath });
