The Rust parser.
NOTE: The crate is undergoing refactors, don’t believe everything the docs say :-)
The parser doesn’t know about concrete representation of tokens and syntax
trees. Abstract [TokenSource] and [TreeSink] traits are used instead. As
a consequence, this crate does not contain a lexer.
The Parser struct from the parser module is a cursor into the
sequence of tokens. Parsing routines use Parser to inspect current
state and advance the parsing.
The actual parsing happens in the [grammar] module.
Tests for this crate live in the syntax crate.
Macros§
Structs§
- Input
- Input for the parser – a sequence of tokens.
- Lexed
Str - Output
- Output of the parser – a DFS traversal of a concrete syntax tree.
- Reparser
- A parsing function for a specific braced-block.
Enums§
- Edition
- Prefix
Entry Point - Parse a prefix of the input as a given syntactic construct.
- Step
- StrStep
- Syntax
Kind - The kind of syntax node, e.g.
IDENT,USE_KW, orSTRUCT. - TopEntry
Point - Parse the whole of the input as a given syntactic construct.
