Represents a statement in the language.

Variants

Expression(ExpressionData)

An expression statement. This is the only statement that evaluates to a value.

Function(FunctionData)

A function statement. This is used to construct a function (or a method) value.

If(IfData)

An if statement. This is used to conditionally execute a statement.

Print(PrintData)

A print statement. This is used to print a value to the standard output.

Return(ReturnData)

A return statement. This is used to return from a function (optionally with a value).

Break(BreakData)

A break statement. This is used to break out of a loop.

Var(VarData)

A var statement. This is used to declare a variable.

While(WhileData)

A while statement. This is used to conditionally execute a statement repeatedly.

Block(BlockData)

A block statement. This is used to group statements together like a function body.

Class(ClassData)

A class statement. This is used to declare a class.

Implementations

impl Stmt

pub fn accept<T>(&self, visitor: &mut dyn StmtVisitor<T>) -> T

Accepts a visitor and returns the result of the visit. This is used to implement the visitor pattern.

Trait Implementations

impl Clone for Stmt

fn clone(&self) -> Stmt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stmt

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

Formats the value using the given formatter.

impl PartialEq for Stmt

fn eq(&self, other: &Stmt) -> 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.
