Struct AnonFnExpr 

pub struct AnonFnExpr {
    pub params: Vec<Param>,
    pub return_type: Option<TypeExpr>,
    pub body: BlockExpr,
    pub span: Span,
}

An anonymous function expression (e.g., fn(x: i32) -> i32 { x + 1 }).

ADR-0055: desugars to an anonymous struct with a single __call method and is instantiated as an empty struct literal. Each AnonFn site produces a distinct type.

Fields

params: Vec<Param>

Parameters (all require type annotations, like named functions).

return_type: Option<TypeExpr>

Return type (None means implicit unit (), same as named functions).

body: BlockExpr

Function body (always a block).

span: Span

Span covering the entire fn(...) { ... } expression.

Trait Implementations

impl Clone for AnonFnExpr

fn clone(&self) -> AnonFnExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnonFnExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AnonFnExpr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AnonFnExpr

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

impl Serialize for AnonFnExpr

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
