Struct LemonMint 

pub struct LemonMint { /* private fields */ }

The compiled parser that can be saved to a rust file. Use LemonMintBuilder to build it.

Implementations

impl LemonMint

pub fn gen_rust<W>(&self, out: &mut W) -> Result<()>

where W: Write,

Generate the Rust source code of the parser, writing it to out.

The output is self-contained (no dependency on this crate) and exposes a code module containing the Parser struct and the Token enum. Typically you write it to a file under OUT_DIR from a build script and include! it, or generate it once and commit it.

pub fn gen_log<W>( &self, out: &mut W, basisflag: bool, show_precedence_conflict: bool, ) -> Result<()>

where W: Write,

Write a human-readable report of the generated state machine (classic Lemon’s y.output).

Useful for understanding the parser and for debugging grammar conflicts.

• basisflag - print only the basis configurations of each state, not the full closure.
• show_precedence_conflict - also report conflicts that were resolved by precedence rules.

pub fn gen_y<W>(&self, out: &mut W) -> Result<()>

where W: Write,

Write a normalized copy of the grammar to out: the list of symbols and the rules, without comments or action code. Handy when the grammar was assembled through builder calls and you want to see the equivalent Y-grammar.
