Struct sljs::ast::Program

pub struct Program {
    pub body: BlockStatement,
    /* private fields */
}

Represents a complete top-level JS script.

The only way to create a Program externally is to use LexicalContext::new_program, maybe via Program::parse_from or build::script helpers. This ensures that its bindings are statically analysed.

Fields

body: BlockStatement

Implementations

impl Program

pub fn globals_iter(&self) -> impl Iterator<Item = &Binding>

pub fn bindings_iter(&self) -> BlockBindings<'_>

impl Program

pub fn parse_from<S: SourceNode>(source: &S) -> ParseResult<Program>

Makes a Program from anything that implements SourceNode

e.g. from a JSON ESTree.

Trait Implementations

impl Debug for Program

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

Formats the value using the given formatter.

impl Interpretable for Program

fn interpret(&self, heap: &mut Heap) -> JSResult<Interpreted>

Interpret self on the heap, potentially to a settable Interpreted::Member.

fn evaluate(&self, heap: &mut Heap) -> JSResult<JSValue>

A wrapper for .interpret that also resolves the result to JSValue

impl PartialEq<Program> for Program

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl ToESTree for Program

fn to_estree(&self) -> JSON

impl<T, F> TryFrom<Builder<T, F>> for Program where
    Statement: From<T>,
    F: FnOnce(&mut LexicalContext) -> ParseResult<T>, 

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(builder: Builder<T, F>) -> Result<Self, ParseError>

Performs the conversion.

impl<F> TryFrom<Builder<Vec<Statement, Global>, F>> for Program where
    F: FnOnce(&mut LexicalContext) -> ParseResult<Vec<Statement>>, 

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(builder: BlockBuilder<F>) -> Result<Self, ParseError>

Performs the conversion.

impl TryFrom<Expression> for Program

type Error = ParseError
