Struct JsProgram 

pub struct JsProgram { /* private fields */ }

Reusable OXC-backed JavaScript/TypeScript program handle.

This owns the source text and arena allocator required by the parsed OXC AST so downstream tools can inspect the AST without reparsing or converting through ESTree JSON.

Implementations

impl JsProgram

pub fn parse(source: impl Into<Box<str>>, source_type: SourceType) -> Self

Parse JavaScript or TypeScript source into a program AST.

pub fn parse_with_options( source: impl Into<Box<str>>, source_type: SourceType, options: ParseOptions, ) -> Self

Parse with explicit OXC parser options.

pub fn source(&self) -> &str

Return the original source text.

pub fn source_type(&self) -> SourceType

Return the OXC source type used for parsing.

pub fn program(&self) -> &Program<'_>

Return the parsed OXC program AST.

pub fn errors(&self) -> &[OxcDiagnostic]

Return any parse errors (the program may still be partially valid).

pub fn panicked(&self) -> bool

Return true if the parser panicked during parsing.

pub fn is_flow_language(&self) -> bool

Return true if the source uses Flow type annotations.

pub fn parser_return(&self) -> &ParserReturn<'_>

Access the full parser return for consumers that need module records, irregular whitespaces, or other parser metadata.

pub fn to_estree_json( &self, full_source: &str, offset: usize, script_tag_end: usize, ) -> String

Serialize the full Program AST to ESTree JSON, with span offsets adjusted by offset (typically content_start from the Script node), and loc fields injected.

full_source is the full .svelte source. offset is content_start (byte position where script content begins). script_tag_end is the byte position after the closing </script> tag.

impl JsProgram

pub fn statement(&self, index: usize) -> Option<&Statement<'_>>

pub fn statement_source(&self, index: usize) -> Option<&str>

pub fn variable_declaration( &self, index: usize, ) -> Option<&VariableDeclaration<'_>>

Trait Implementations

impl Debug for JsProgram

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

Formats the value using the given formatter.

impl PartialEq for JsProgram

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
