Trait Implementations

impl Debug for DerivePlugin

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DerivePlugin

fn default() -> DerivePlugin

Returns the “default value” for a type.

impl MacroPlugin for DerivePlugin

fn generate_code<'db>( &self, db: &'db dyn Database, item_ast: ModuleItem<'db>, metadata: &MacroPluginMetadata<'_>, ) -> PluginResult<'db>

Generates code for an item. If no code should be generated returns None. Otherwise, returns PluginResult with the generated virtual submodule.

fn declared_attributes<'db>(&self, db: &'db dyn Database) -> Vec<SmolStrId<'db>>

Attributes this plugin uses. Attributes the plugin uses without declaring here are likely to cause a compilation error for unknown attribute. Note: They may not cause a diagnostic if some other plugin declares such attribute, but plugin writers should not rely on that.

fn declared_derives<'db>(&self, db: &'db dyn Database) -> Vec<SmolStrId<'db>>

Derives this plugin supplies. Any derived classes the plugin supplies without declaring here are likely to cause a compilation error for unknown derive. Note: They may not cause a diagnostic if some other plugin declares such derive, but plugin writers should not rely on that.

fn executable_attributes<'db>( &self, _db: &'db (dyn Database + 'static), ) -> Vec<SmolStrId<'db>>

Attributes that should mark the function as an executable. Functions marked with executable attributes will be listed in a dedicated field in the generated program. Must return a subset of declared_attributes. This mechanism is optional.

fn phantom_type_attributes<'db>( &self, _db: &'db (dyn Database + 'static), ) -> Vec<SmolStrId<'db>>

Attributes that mark a type as a phantom type. Must return a subset of declared_attributes. This mechanism is optional.

fn plugin_type_id(&self) -> TypeId

A TypeId of the plugin, used to compare the concrete types of plugins given as trait objects.
