Struct deno_ast::ParsedSource

pub struct ParsedSource { /* private fields */ }

A parsed source containing an AST, comments, and possibly tokens.

Note: This struct is cheap to clone.

Implementations

impl ParsedSource

pub fn analyze_cjs(&self) -> CjsAnalysis

Analyzes the script for CommonJS exports and re-exports based on similar functionality to cjs-module-lexer (https://github.com/nodejs/cjs-module-lexer).

Note: This will panic if called on a non-script.

impl ParsedSource

pub fn specifier(&self) -> &str

Gets the module specifier of the module.

pub fn media_type(&self) -> MediaType

Gets the media type of the module.

pub fn text_info(&self) -> &SourceTextInfo

Gets the text content of the module.

pub fn program(&self) -> Arc<Program>

Gets the parsed program.

pub fn program_ref(&self) -> &Program

Gets the parsed program as a reference.

pub fn module(&self) -> &Module

Gets the parsed module.

This will panic if the source is not a module.

pub fn script(&self) -> &Script

Gets the parsed script.

This will panic if the source is not a script.

pub fn comments(&self) -> &MultiThreadedComments

Gets the comments found in the source file.

pub fn get_leading_comments(&self) -> Vec<Comment>

Get the source’s leading comments, where triple slash directives might be located.

pub fn tokens(&self) -> &[TokenAndSpan]

Gets the tokens found in the source file.

This will panic if tokens were not captured during parsing.

pub fn top_level_context(&self) -> SyntaxContext

Gets the top level context used when parsing with scope analysis.

This will panic if the source was not parsed with scope analysis.

pub fn unresolved_context(&self) -> SyntaxContext

Gets the unresolved context used when parsing with scope analysis.

This will panic if the source was not parsed with scope analysis.

pub fn diagnostics(&self) -> &Vec<Diagnostic>

Gets extra non-fatal diagnostics found while parsing.

pub fn is_module(&self) -> bool

Gets if this source is a module.

pub fn is_script(&self) -> bool

Gets if this source is a script.

impl ParsedSource

pub fn with_view<'a, T>(&self, with_view: impl FnOnce(Program<'a>) -> T) -> T

Gets a dprint-swc-ext view of the module.

This provides a closure to examine an “ast view” of the swc AST which has more helper methods and allows for going up the ancestors of a node.

impl ParsedSource

pub fn transpile(&self, options: &EmitOptions) -> Result<TranspiledSource>

Transform a TypeScript file into a JavaScript file.

Trait Implementations

impl Clone for ParsedSource

fn clone(&self) -> ParsedSource

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParsedSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
