Trait Implementations

impl Clone for MacroPluginLongId

fn clone(&self) -> MacroPluginLongId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MacroPluginLongId

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

Formats the value using the given formatter.

impl Hash for MacroPluginLongId

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Intern<'a, dyn DefsGroup + 'a, MacroPluginId> for MacroPluginLongId

fn intern( self, db: &(impl Upcast<dyn DefsGroup + 'a> + ?Sized), ) -> MacroPluginId

impl<'a> LookupIntern<'a, dyn DefsGroup + 'a, MacroPluginLongId> for MacroPluginId

fn lookup_intern( &self, db: &(impl Upcast<dyn DefsGroup + 'a> + ?Sized), ) -> MacroPluginLongId

impl MacroPlugin for MacroPluginLongId

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.

fn plugin_type_id(&self) -> TypeId

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

impl PartialEq for MacroPluginLongId

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
