Trait Implementations

impl Debug for PanicablePlugin

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

Formats the value using the given formatter.

impl Default for PanicablePlugin

fn default() -> PanicablePlugin

Returns the “default value” for a type.

impl MacroPlugin for PanicablePlugin

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

Generates code for an item. If no code should be generated returns None. Otherwise, returns (virtual_module_name, module_content), and a virtual submodule with that name and content should be created.

fn declared_attributes(&self) -> Vec<String>

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(&self) -> Vec<String>

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(&self) -> Vec<String>

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(&self) -> Vec<String>

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