Struct OptionalOperation 

pub struct OptionalOperation { /* private fields */ }

Operation within an Optional chain.

An operation within an Optional chain can be either shorted or non-shorted. A shorted operation (?.item) will force the expression to return undefined if the target is undefined or null. In contrast, a non-shorted operation (.prop) will try to access the property, even if the target is undefined or null.

Implementations

impl OptionalOperation

pub const fn new(kind: OptionalOperationKind, shorted: bool, span: Span) -> Self

Creates a new OptionalOperation.

pub const fn kind(&self) -> &OptionalOperationKind

Gets the kind of operation.

pub const fn shorted(&self) -> bool

Returns true if the operation short-circuits the Optional chain when the target is undefined or null.

Trait Implementations
