Struct JSXAttribute 

#[repr(C)]
pub struct JSXAttribute<'a> {
    pub span: Span,
    pub name: JSXAttributeName<'a>,
    pub value: Option<JSXAttributeValue<'a>>,
}

JSX Attribute

An attribute in a JSX opening tag. May or may not have a value. Part of JSXAttributeItem.

Example

// `has-no-value` is a JSXAttribute with no value.
<Component has-no-value foo="foo" />
//                 name ^^^ ^^^^ value

Fields

span: Span

Node location in source code

name: JSXAttributeName<'a>

The name of the attribute. This is a prop in React-like applications.

value: Option<JSXAttributeValue<'a>>

The value of the attribute. This can be a string literal, an expression, or an element. Will be None for boolean-like attributes (e.g. <button disabled />).

Implementations

impl JSXAttribute<'_>

pub fn is_identifier(&self, name: &str) -> bool

Returns true if this attribute’s name is the expected name.

Use JSXAttribute::is_identifier_ignore_case if you want to ignore upper/lower case differences.

pub fn is_identifier_ignore_case(&self, name: &str) -> bool

Returns true if this attribute’s name is the expected name, ignoring casing.

pub fn is_key(&self) -> bool

Returns true if this is a React key.

Example

<Foo key="value" /> // -> `true`
<Foo bar="value" /> // -> `false`

Trait Implementations

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

type Cloned = JSXAttribute<'new_alloc>

The type of the cloned object.

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

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

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for JSXAttribute<'a>

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

Create a dummy JSXAttribute.

Has cost of making 1 allocation (24 bytes).

impl Gen for JSXAttribute<'_>

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 JSXAttribute<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for JSXAttribute<'_>

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

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

impl<'a> TakeIn<'a> for JSXAttribute<'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.
