Struct FunctionType

pub struct FunctionType {
    pub arrow: Token,
    pub type_name: Token,
    pub is_array: bool,
    pub is_nullable: bool,
}

Represents a function type annotation in the AST.

A function type includes an arrow (->) and the return type.

Fields

arrow: Token

The token representing the arrow (->) in the function type.

type_name: Token

The token representing the return type.

is_array: bool

Is this type an array?

is_nullable: bool

Is nullable?

Implementations

impl FunctionType

pub fn new( arrow: Token, type_name: Token, is_array: bool, is_nullable: bool, ) -> FunctionType

Creates a new function type annotation.

Arguments

• arrow - The token representing the arrow (->).
• type_name - The token representing the return type.

Returns

A new FunctionType instance.

Trait Implementations

impl Clone for FunctionType

fn clone(&self) -> FunctionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionType

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

Formats the value using the given formatter.

impl PartialEq for FunctionType

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