Struct Block 

pub struct Block { /* private fields */ }

A block statement (or compound statement in other languages) is used to group zero or more statements.

The block statement is often called compound statement in other languages. It allows you to use multiple statements where ECMAScript expects only one statement. Combining statements into blocks is a common practice in ECMAScript. The opposite behavior is possible using an empty statement, where you provide no statement, although one is required.

More information:

• ECMAScript reference
• MDN documentation

Implementations

impl Block

pub const fn statement_list(&self) -> &StatementList

Gets the list of statements and declarations in this block.

pub const fn scope(&self) -> Option<&Scope>

Gets the scope of the block.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Block

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Default for Block

fn default() -> Block

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Block

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a Block> for NodeRef<'a>

fn from(node: &'a Block) -> NodeRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a mut Block> for NodeRefMut<'a>

fn from(node: &'a mut Block) -> NodeRefMut<'a>

Converts to this type from the input type.

impl From<Block> for Finally

fn from(block: Block) -> Self

Converts to this type from the input type.

impl From<Block> for Statement

fn from(block: Block) -> Self

Converts to this type from the input type.

impl<T> From<T> for Block

where T: Into<StatementList>,

fn from(list: T) -> Self

Converts to this type from the input type.

impl PartialEq for Block

fn eq(&self, other: &Block) -> 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 Serialize for Block

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToIndentedString for Block

fn to_indented_string(&self, interner: &Interner, indentation: usize) -> String

Converts the element to a string using an interner, with the given indentation.

impl VisitWith for Block

fn visit_with<'a, V>(&'a self, visitor: &mut V) -> ControlFlow<V::BreakTy>

where V: Visitor<'a>,

Visit this node with the provided visitor.

fn visit_with_mut<'a, V>( &'a mut self, visitor: &mut V, ) -> ControlFlow<V::BreakTy>

where V: VisitorMut<'a>,

Visit this node with the provided visitor mutably, allowing the visitor to modify private fields.
