Struct VarData 

pub struct VarData {
    pub parent: SymbolId,
    pub kind: VarKind,
    pub line: u32,
    pub is_mut: bool,
}

Variable data (12 bytes) - DOD optimized.

Each variable is identified by its SymbolId (registered via SymbolRegistry::register_var). The parent symbol and variable name can be retrieved via the SymbolRegistry.

DOD Design

• parent: Reference to containing symbol (function/method/struct)
• kind: Variable classification
• line: Source location for diagnostics
• is_mut: Whether binding was declared let mut (set by builder from PurePattern::Ident { is_mut }, used by UnnecessaryClone to suppress FPs on mutable working copies)

Variable’s SymbolId is stored in VarSymbolMapping (VarId ↔ SymbolId).

Fields

parent: SymbolId

Parent symbol (function, method, struct, etc.) that contains this variable.

kind: VarKind

Variable kind (parameter, local, temp, field, etc.).

line: u32

Line number where defined (0 = unknown).

is_mut: bool

Whether the binding is declared mut (e.g. let mut x = ...).

Trait Implementations

impl Clone for VarData

fn clone(&self) -> VarData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VarData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VarData

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for VarData

impl Eq for VarData
