Struct FunctionParameter 

pub struct FunctionParameter {
    pub pattern: DestructurePattern,
    pub is_const: bool,
    pub is_reference: bool,
    pub is_mut_reference: bool,
    pub is_out: bool,
    pub type_annotation: Option<TypeAnnotation>,
    pub default_value: Option<Expr>,
}

Fields

pattern: DestructurePattern

is_const: bool

is_reference: bool

is_mut_reference: bool

Whether this is an exclusive (mutable) reference: &mut x Only meaningful when is_reference is true.

is_out: bool

Whether this is an out parameter (C out-pointer pattern). Only valid on extern C fn declarations. The compiler auto-generates cell allocation, C call, value readback, and cell cleanup.

type_annotation: Option<TypeAnnotation>

default_value: Option<Expr>

Implementations

impl FunctionParameter

pub fn simple_name(&self) -> Option<&str>

Get the simple parameter name if this is a simple identifier pattern

pub fn get_identifiers(&self) -> Vec<String>

Get all identifiers bound by this parameter (for destructuring patterns)

pub fn span(&self) -> Span

Get the span for this parameter

Trait Implementations

impl Clone for FunctionParameter

fn clone(&self) -> FunctionParameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionParameter

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionParameter

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FunctionParameter

fn eq(&self, other: &FunctionParameter) -> 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 FunctionParameter

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
