Struct Case 

pub struct Case { /* private fields */ }

A case clause inside a Switch statement, as defined by the spec.

Even though every Case body is a StatementList, it doesn’t create a new lexical environment. This means any variable declared in a Case will be considered as part of the lexical environment of the parent Switch block.

Implementations

impl Case

pub const fn new(condition: Expression, body: StatementList) -> Self

Creates a regular Case AST node.

pub const fn default(body: StatementList) -> Self

Creates a default Case AST node.

pub const fn condition(&self) -> Option<&Expression>

Gets the condition of the case.

If it’s a regular case returns Some with the Expression, otherwise None is returned if it’s the default case.

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

Gets the statement listin the body of the case.

pub const fn is_default(&self) -> bool

Check if the case is the default case.

Trait Implementations
