Struct Generator 

pub struct Generator<'s, SI: SyntaxInterpreter> { /* private fields */ }

A helper type that consumes the interpreter and generates the whole code block with it. The block itself is generated with prelude and postlude callbacks. E.g. for Python this snippet can be used to generate the interpret method:

record_type
    .syntax
    .bind(PythonRecordInterpreter::new(&record_type))
    .prelude(|intrp, out| {
        bufwriteln!(out, :>4, "def interpret(self):");
        intrp.offset = 8;
    })
    // There is no need to use the .postlude(|intrp, out|) callback because
    // in Python functions and methods don't have closing brackets or keywords
    .generate()?;

To construct the generator witt a bind method import BindExt trait.

Implementations

impl<'s, SI: SyntaxInterpreter> Generator<'s, SI>

pub fn new(syntax: &'s str, interpreter: SI) -> Self

pub fn prelude<F>(self, f: F) -> Self

where F: 's + FnOnce(&mut SI, &mut String) -> SyntaxInterpreterResult<'s, (), SI::Error>,

pub fn postlude<F>(self, f: F) -> Self

where F: 's + FnOnce(&mut SI, &mut String) -> SyntaxInterpreterResult<'s, (), SI::Error>,

pub fn generate(self) -> SyntaxInterpreterResult<'s, Option<String>, SI::Error>
