Struct PassBuilder

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

Builder is used to create a high performance Compiler.

Implementations

impl<'a, 'b, P: Pass> 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, (P, N)>

where N: Pass,

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, (P, impl Pass)>

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

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

pub fn preset_env(self, env: Option<Config>) -> Self

pub fn regenerator(self, config: Config) -> Self

pub fn finalize<'cmt>( self, syntax: Syntax, module: Option<ModuleConfig>, comments: Option<&'cmt dyn Comments>, resolver: Option<(FileName, Arc<dyn ImportResolver>)>, ) -> impl 'cmt + Pass

where P: 'cmt,

Arguments
