Struct swc::PassBuilder

pub struct PassBuilder<'a, 'b, P: Fold> { /* fields omitted */ }

Builder is used to create a high performance Compiler.

Implementations

impl<'a, 'b, P: Fold> PassBuilder<'a, 'b, P>

pub fn new(
    cm: &'a Arc<SourceMap>,
    handler: &'b Handler,
    loose: bool,
    global_mark: Mark,
    pass: P
) -> Self

pub fn then<N>(self, next: N) -> PassBuilder<'a, 'b, AndThen<P, N>> where
    N: Fold, 

pub fn skip_helper_injection(mut self: Self, skip: bool) -> Self

pub fn fixer(mut self: Self, enable: bool) -> Self

Note: fixer is enabled by default.

pub fn hygiene(mut self: Self, enable: bool) -> Self

Note: hygiene is enabled by default.

pub fn const_modules(
    self,
    globals: HashMap<JsWord, HashMap<JsWord, String>>
