Struct ra_ap_proc_macro_api::ProcMacro

pub struct ProcMacro { /* private fields */ }

A handle to a specific macro (a #[proc_macro] annotated function).

It exists within a context of a specific [ProcMacroProcess] – currently we share a single expander process for all macros.

Implementations

impl ProcMacro

pub fn name(&self) -> &str

pub fn kind(&self) -> ProcMacroKind

pub fn expand( &self, subtree: &Subtree<Span>, attr: Option<&Subtree<Span>>, env: Vec<(String, String)>, def_site: Span, call_site: Span, mixed_site: Span ) -> Result<Result<Subtree<Span>, PanicMessage>, ServerError>

Trait Implementations

impl Clone for ProcMacro

fn clone(&self) -> ProcMacro

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProcMacro

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

Formats the value using the given formatter.

impl PartialEq for ProcMacro

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

This method tests for self and other values to be equal, and is used by ==.

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

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