Struct Parser

pub struct Parser { /* private fields */ }

Parser type

This is a high level object that wraps the file loader/parser.his doesn’t do much special. The ParseSess object must be borrowed by the parsing processing. So this class ensures this is happening without much drama or requiring you to peer into the syntex_syntax internals.

There are methods to load external files, and borrow a string. That’ll be immediately cloned just fyi.

Implementations

impl Parser

pub fn new() -> Parser

Construct a new parser.

pub fn get_tokens<'a>(&'a self, path: &str) -> Result<Vec<Token>, Fault<'a>>

Get a vector of all tokens, or get an error. Loads a file

pub fn get_tokentree<'a>( &'a self, path: &str, ) -> Result<Vec<TokenTree>, Fault<'a>>

Get the token tree, or get an error. Loads a file

pub fn get_tokens_local<'a>( &'a self, code: &str, ) -> Result<Vec<Token>, Fault<'a>>

Get a flat list of tokens, while using pre-loaded code. Does not file IO

pub fn get_tokenstree_local<'a>( &'a self, code: &str, ) -> Result<Vec<TokenTree>, Fault<'a>>

Get token tree, while using pre-loaded code. Does not file IO
