Crate syntax [−] [src]

Unstable (rustc_private)

The Rust parser and macro expander.

Note

This API is completely unstable and subject to change.

abi	[Unstable]
ast	[Unstable]
attr	[Unstable]
codemap	[Unstable] The CodeMap tracks all the source code used within a single crate, mapping from integer byte positions to the original source code location. Each bit of source parsed during crate parsing (typically files, in-memory strings, or various bits of macro expansion) cover a continuous range of bytes in the CodeMap and are represented by FileMaps. Byte positions are stored in `spans` and used pervasively in the compiler. They are absolute positions within the CodeMap, which upon request can be converted to line and column information, source code snippets, etc.
config	[Unstable]
diagnostics	[Unstable]
entry	[Unstable]
errors	[Unstable]
ext	[Unstable]
feature_gate	[Unstable] Feature gating
fold	[Unstable] A Folder represents an AST->AST fold; it accepts an AST piece, and returns a piece of the same type. So, for instance, macro expansion is a Folder that walks over an AST and produces another AST.
parse	[Unstable] The main parser interface
print	[Unstable]
ptr	[Unstable] The AST pointer
show_span	[Unstable] Span debugger
std_inject	[Unstable]
str	[Unstable]
syntax	[Unstable]
test	[Unstable]
util	[Unstable]
visit	[Unstable] 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.
