Struct rustc::plugin::registry::RegistryUnstable
[-] [+]
[src]
pub struct Registry<'a> { pub sess: &'a Session, // some fields omitted }
Structure used to register plugins.
A plugin registrar function takes an &mut Registry
and should call
methods to register its plugins.
This struct has public fields and other methods for use by rustc
itself. They are not documented here, and plugin authors should
not use them.
Fields
sess | Compiler session. Useful if you want to emit diagnostic messages from the plugin registrar. |
Methods
impl<'a> Registry<'a>
fn args<'b>(&'b self) -> &'b Vec<P<MetaItem>>
Get the plugin's arguments, if any.
These are specified inside the plugin
crate attribute as
#![plugin(my_plugin_name(... args ...))]
fn register_syntax_extension(&mut self, name: Name, extension: SyntaxExtension)
Register a syntax extension of any kind.
This is the most general hook into libsyntax
's expansion behavior.
fn register_macro(&mut self, name: &str, expander: MacroExpanderFn)
Register a macro of the usual kind.
This is a convenience wrapper for register_syntax_extension
.
It builds for you a NormalTT
that calls expander
,
and also takes care of interning the macro's name.
fn register_lint_pass(&mut self, lint_pass: LintPassObject)
Register a compiler lint pass.
fn register_lint_group(&mut self, name: &'static str, to: Vec<&'static Lint>)
Register a lint group.
