Struct Try 

pub struct Try { /* private fields */ }

The try...catch statement marks a block of statements to try and specifies a response should an exception be thrown.

The try statement consists of a try-block, which contains one or more statements. {} must always be used, even for single statements. At least one catch-block, or a finally-block, must be present.

More information:

• ECMAScript reference
• MDN documentation

Implementations

impl Try

pub const fn new(block: Block, handler: ErrorHandler) -> Self

Creates a new Try AST node.

pub const fn block(&self) -> &Block

Gets the try block.

pub const fn catch(&self) -> Option<&Catch>

Gets the catch block, if any.

pub const fn finally(&self) -> Option<&Finally>

Gets the finally block, if any.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Try

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 Try

fn clone(&self) -> Try

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Try

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Try

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 Try> for NodeRef<'a>

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl From<Try> for Statement

fn from(try_catch: Try) -> Self

Converts to this type from the input type.

impl PartialEq for Try

fn eq(&self, other: &Try) -> 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 Try

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 Try

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 Try

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.
