Struct swc::PassBuilder

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

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,
    assumptions: Assumptions,
    top_level_mark: Mark,
    unresolved_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(self, skip: bool) -> Self

pub fn minify(self, options: Option<JsMinifyOptions>) -> Self

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

Note: fixer is enabled by default.

pub fn hygiene(self, config: Option<Config>) -> Self

Note: hygiene is enabled by default.

If you pass None to this method, the hygiene pass will be disabled.

pub fn const_modules(
    self,
    globals: FxHashMap<JsWord, FxHashMap<JsWord, String>>
) -> PassBuilder<'a, 'b, impl Fold>

pub fn inline_globals(
    self,
    c: GlobalPassOption
) -> PassBuilder<'a, 'b, impl Fold>

pub fn target(self, target: EsVersion) -> Self

    paths: Vec<(String, Vec<String>)>,
    base: &FileName,
    syntax: Syntax,
    module: Option<ModuleConfig>,
    comments: Option<&'cmt SingleThreadedComments>
) -> impl 'cmt + Foldwhere
    P: 'cmt,

Arguments
