Crate lexx [−] [src]
Rust Lex
The goal of this crate is to make interacting with the AST construct parts of Rust a little easier. It is more or less a high level wrapping around the various syntex_syntax crates. Those crates have partially complete documentation. This crate is the result of a few days of trial and error.
Some of the public types will force you to jump into the syntex crates, but it should only be inspecting tokens/error messages.
Structs
Delimited |
A delimited sequence of token trees |
DiagnosticBuilder |
Used for emitting structured error messages and other diagnostic information. |
IOErr |
The error type for I/O operations of the |
Parser |
Parser type |
SequenceRepetition |
A sequence of token trees |
Enums
DelimToken |
A delimiter token |
Fault |
Error Wrapper |
Token | |
TokenTree |
When the main rust parser encounters a syntax-extension invocation, it parses the arguments to the invocation as a token-tree. This is a very loose structure, such that all sorts of different AST-fragments can be passed to syntax extensions using a uniform type. |
Functions
dr |
For deconstructor a branch of TokenTree into a usable type |
flatten_token_tree |
Flatten TokenTree |
sr |
For deconstructor a branch of TokenTree into a usable type |
tt |
For dispatching to dr/sr for deconstructing TokenTrees |
