Struct VariableDecl 

pub struct VariableDecl {
    pub kind: VarKind,
    pub is_mut: bool,
    pub pattern: DestructurePattern,
    pub type_annotation: Option<TypeAnnotation>,
    pub value: Option<Expr>,
    pub ownership: OwnershipModifier,
}

Fields

kind: VarKind

is_mut: bool

Explicit mutability: let mut x = ... When false with VarKind::Let, the binding is immutable. When VarKind::Var, mutability is inferred from usage.

pattern: DestructurePattern

type_annotation: Option<TypeAnnotation>

value: Option<Expr>

ownership: OwnershipModifier

Explicit ownership modifier on the initializer: let x = move y or let x = clone y

Trait Implementations

impl Clone for VariableDecl

fn clone(&self) -> VariableDecl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariableDecl

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VariableDecl

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VariableDecl

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
