String literal

https://tc39.es/ecma262/#sec-literals-string-literals

Fields

span: Span

Node location in source code

value: Atom<'a>

The value of the string.

Any escape sequences in the raw code are unescaped.

raw: Option<Atom<'a>>

The raw string as it appears in source code.

None when this ast node is not constructed from the parser.

lone_surrogates: bool

The string value contains lone surrogates.

value is encoded using \u{FFFD} (the lossy replacement character) as an escape character. Lone surrogates are encoded as \u{FFFD}XXXX, where XXXX is the code unit in hex. The lossy escape character itself is encoded as \u{FFFD}fffd.

Implementations

impl StringLiteral<'_>

pub fn is_string_well_formed_unicode(&self) -> bool

Static Semantics: IsStringWellFormedUnicode test for \uD800-\uDFFF

See: https://tc39.es/ecma262/multipage/abstract-operations.html#sec-isstringwellformedunicode

Trait Implementations

impl AsRef<str> for StringLiteral<'_>

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Clone for StringLiteral<'a>

fn clone(&self) -> StringLiteral<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

type Cloned = StringLiteral<'new_alloc>

The type of the cloned object.

fn clone_in( &self, allocator: &'new_alloc Allocator, ) -> <StringLiteral<'_> 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, ) -> <StringLiteral<'_> 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 StringLiteral<'_>

fn content_eq(&self, other: &StringLiteral<'_>) -> 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 StringLiteral<'a>

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

Formats the value using the given formatter.

impl Display for StringLiteral<'_>

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for StringLiteral<'a>

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

Create a dummy StringLiteral.

Does not allocate any data into arena.

impl<'a> GatherNodeParts<'a> for StringLiteral<'a>

fn gather<F>(&self, f: &mut F)

where F: FnMut(&str),

impl Gen for StringLiteral<'_>

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 StringLiteral<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for StringLiteral<'_>

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

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

impl<'a> TakeIn<'a> for StringLiteral<'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<'a> ToJsString<'a> for StringLiteral<'a>

fn to_js_string(&self, _ctx: &impl GlobalContext<'a>) -> Option<Cow<'a, str>>

impl UnstableAddress for StringLiteral<'_>

fn unstable_address(&self) -> Address

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