Struct ArrowFunctionExpr 

#[non_exhaustive]
pub struct ArrowFunctionExpr {
    pub is_static: bool,
    pub by_ref: bool,
    pub params: Box<[Param]>,
    pub missing_param_list: bool,
    pub return_type: Option<TypeHint>,
    pub body: Box<Expr>,
    pub attributes: Box<[Attribute]>,
}

An fn arrow function.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

is_static: bool

Whether declared static.

by_ref: bool

Whether it returns by reference.

params: Box<[Param]>

Parameters.

missing_param_list: bool

true when the parameter list is missing its (, which PHP rejects.

return_type: Option<TypeHint>

Declared return type.

body: Box<Expr>

Result expression.

attributes: Box<[Attribute]>

Attributes on the arrow function.

Implementations

impl ArrowFunctionExpr

pub fn new(body: Box<Expr>) -> Self

Builds a ArrowFunctionExpr from its identifying fields with every other field empty. Set the rest by assignment, as with Param::new.

Trait Implementations

impl Clone for ArrowFunctionExpr

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArrowFunctionExpr

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

Formats the value using the given formatter.

impl Serialize for ArrowFunctionExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
