🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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

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.

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.
