Struct If 

pub struct If { /* private fields */ }

The if statement executes a statement if a specified condition is truthy. If the condition is falsy, another statement can be executed.

Multiple if...else statements can be nested to create an else if clause.

Note that there is no elseif (in one word) keyword in JavaScript.

More information:

• ECMAScript reference
• MDN documentation

Implementations

impl If

pub fn cond(&self) -> &Node

pub fn body(&self) -> &Node

pub fn else_node(&self) -> Option<&Node>

pub fn new<C, B, E, OE>(condition: C, body: B, else_node: OE) -> Self

where C: Into<Node>, B: Into<Node>, E: Into<Node>, OE: Into<Option<E>>,

Creates an If AST node.

Trait Implementations

impl Clone for If

fn clone(&self) -> If

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for If

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

Formats the value using the given formatter.

impl Display for If

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

Formats the value using the given formatter.

impl Drop for If

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Executable for If

fn run(&self, context: &mut Context) -> JsResult<JsValue>

Runs this executable in the given context.

impl Finalize for If

fn finalize(&self)

impl From<If> for Node

fn from(if_stm: If) -> Node

Converts to this type from the input type.

impl PartialEq for If

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for If

impl Trace for If

unsafe fn trace(&self)

Marks all contained Gcs.

unsafe fn root(&self)

Increments the root-count of all contained Gcs.

unsafe fn unroot(&self)

Decrements the root-count of all contained Gcs.

fn finalize_glue(&self)

Runs Finalize::finalize() on this object and all contained subobjects
