Struct Program 

#[repr(C)]
pub struct Program<'a> {
    pub span: Span,
    pub source_text: &'a str,
    pub comments: Vec<'a, Comment>,
    pub hashbang: Option<Hashbang<'a>>,
    pub directives: Vec<'a, Directive<'a>>,
    pub body: Vec<'a, Statement<'a>>,
    pub scope_id: Cell<Option<ScopeId>>,
    pub source_type: SourceType,
}

Represents the root of a JavaScript abstract syntax tree (AST), containing metadata about the source, directives, top-level statements, and scope information.

Fields

span: Span

source_text: &'a str

comments: Vec<'a, Comment>

Sorted comments

hashbang: Option<Hashbang<'a>>

directives: Vec<'a, Directive<'a>>

body: Vec<'a, Statement<'a>>

scope_id: Cell<Option<ScopeId>>

source_type: SourceType

Implementations

impl Program<'_>

pub fn is_empty(&self) -> bool

Returns true if this program has no statements or directives.

pub fn has_use_strict_directive(&self) -> bool

Returns true if this program has a "use strict" directive.

impl Program<'_>

pub fn scope_id(&self) -> ScopeId

Get ScopeId of Program.

Only use this method on a post-semantic AST where ScopeIds are always defined.

Panics

Panics if scope_id is None.

pub fn set_scope_id(&self, scope_id: ScopeId)

Set ScopeId of Program.

Trait Implementations

impl<'new_alloc> CloneIn<'new_alloc> for Program<'_>

type Cloned = Program<'new_alloc>

The type of the cloned object.

fn clone_in( &self, allocator: &'new_alloc Allocator, ) -> <Program<'_> as CloneIn<'new_alloc>>::Cloned

Clone self into the given allocator. allocator may be the same one that self is already in.

fn clone_in_with_semantic_ids( &self, allocator: &'new_alloc Allocator, ) -> <Program<'_> as CloneIn<'new_alloc>>::Cloned

Almost identical as clone_in, but for some special type, it will also clone the semantic ids. Please use this method only if you make sure semantic info is synced with the ast node.

impl ContentEq for Program<'_>

fn content_eq(&self, other: &Program<'_>) -> bool

This method tests for contents of self and other to be equal.

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

This method tests for contents of self and other not to be equal. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Debug for Program<'a>

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for Program<'a>

fn dummy(allocator: &'a Allocator) -> Program<'a>

Create a dummy Program.

Does not allocate any data into arena.

impl Gen for Program<'_>

fn gen(&self, p: &mut Codegen<'_>, ctx: Context)

Generate code for an AST node.

fn print(&self, p: &mut Codegen<'_>, ctx: Context)

Generate code for an AST node. Alias for gen.

impl GetSpan for Program<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for Program<'_>

fn span_mut(&mut self) -> &mut Span

Get a mutable reference to an AST node’s Span.

impl<'a> TakeIn<'a> for Program<'a>

fn take_in<A>(&mut self, allocator_accessor: A) -> Self

where A: AllocatorAccessor<'a>,

Replace node with a dummy.

fn take_in_box<A>(&mut self, allocator_accessor: A) -> Box<'a, Self>

where A: AllocatorAccessor<'a>,

Replace node with a boxed dummy.

impl UnstableAddress for Program<'_>

fn unstable_address(&self) -> Address

Get the memory Address of a reference to an AST node in arena, which is not necessarily stable.
