Struct Syntax 

pub struct Syntax {
    pub file_kind: FileKind,
    pub top_level_await: bool,
    pub global_return: bool,
    pub class_fields: bool,
    pub decorators: bool,
}

A structure describing the syntax features the parser will accept. The default is an ECMAScript 2021 Script without any proposals.

Fields

file_kind: FileKind

top_level_await: bool

global_return: bool

class_fields: bool

decorators: bool

pub fn top_level_await(self) -> Self

pub fn global_return(self) -> Self

pub fn class_fields(self) -> Self

pub fn decorators(self) -> Self

pub fn script(self) -> Self

Trait Implementations

impl Clone for Syntax

fn clone(&self) -> Syntax

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Syntax

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

Formats the value using the given formatter.

impl Default for Syntax

fn default() -> Syntax

Returns the “default value” for a type.

impl From<FileKind> for Syntax

fn from(kind: FileKind) -> Self

Converts to this type from the input type.

impl Hash for Syntax

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Syntax

fn eq(&self, other: &Syntax) -> 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.

impl Copy for Syntax

impl Eq for Syntax

impl StructuralPartialEq for Syntax
