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.

Get the plugin's arguments, if any.
These are specified inside the plugin
crate attribute as
#![plugin(my_plugin_name(... args ...))]
Returns empty slice in case the plugin was loaded
with --extra-plugins

Register a syntax extension of any kind.
This is the most general hook into libsyntax
's expansion behavior.

pub fn register_custom_derive(&mut self, name: Name, extension: SyntaxExtension)
: replaced by macros 1.1 (RFC 1861)
rustc_private
)This can be used in place of register_syntax_extension
to register legacy custom derives
(i.e. attribute syntax extensions whose name begins with derive_
). Legacy custom
derives defined by this function do not trigger deprecation warnings when used.

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.

Register an LLVM pass.
Registration with LLVM itself is handled through static C++ objects with constructors. This method simply adds a name to the list of passes to execute.

Register an attribute with an attribute type.
Registered attributes will bypass the custom_attribute
feature gate.
Whitelisted
attributes will additionally not trigger the unused_attribute
lint. CrateLevel
attributes will not be allowed on anything other than a crate.
