Modules

ast	The Rust abstract syntax tree module.
attr	Functions dealing with attributes and meta items.
diagnostics
early_buffered_lints	Allows the buffering of lints for later.
entry
expand	Definitions shared by macros / syntax extensions and e.g. librustc.
feature_gate
mut_visit	A MutVisitor represents an AST modification; it accepts an AST piece and and mutates it in place. So, for instance, macro expansion is a MutVisitor that walks over an AST and modifies it.
print
ptr	The AST pointer.
sess	Contains ParseSess which holds state living beyond what one Parser might. It also serves as an input to the parser itself.
show_span	Span debugger
token
tokenstream	Token Streams
util
visit	AST walker. Each overridden visit method has full control over what happens with its node, it can do its own traversal of the node's children, call visit::walk_* to apply the default traversal algorithm, or prevent deeper traversal by doing nothing.

Traits

HashStableContext

Requirements for a StableHashingContext to be used in this crate. This is a hack to allow using the HashStable_Generic derive macro instead of implementing everything in librustc.
