Struct erg_parser::parse::Parser

pub struct Parser { /* private fields */ }

Perform recursive descent parsing.

level is raised by 1 by debug_call_info! in each analysis method and lowered by 1 when leaving (.map_err is called to lower the level).

To enhance error descriptions, the parsing process will continue as long as it’s not fatal.
