Struct ShadowEntry 

pub struct ShadowEntry {
    pub id: ShadowEntryId,
    pub scope: ScopeId,
    pub symbol: StringId,
    pub node: NodeId,
    pub byte_offset: u32,
}

One shadow-chain entry.

Records the function scope that owns the variable, the interned symbol name, the NodeId of the defining Variable or Parameter node, the byte offset of that definition, and a stable dense handle into the owning ShadowTable.

The id field is the position of this entry in the sorted entries slice after derive_shadows has run. It is assigned by the sort and must not be mutated by callers.

Fields

id: ShadowEntryId

Stable dense handle for this entry within its owning ShadowTable. Assigned after sorting; equals ShadowEntryId(idx) where idx is the position of this entry in the sorted entries slice.

scope: ScopeId

The function scope that contains this definition.

symbol: StringId

The interned symbol name of the variable or parameter.

node: NodeId

NodeId of the Variable or Parameter node that introduces the binding at this offset.

byte_offset: u32

Byte offset of the definition site within its source file.

Entries within the same (scope, symbol) chain are sorted by this field in ascending order; effective_binding performs a reverse-scan to find the last entry whose offset is strictly less than the query offset.

Trait Implementations

impl Clone for ShadowEntry

fn clone(&self) -> ShadowEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShadowEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ShadowEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ShadowEntry

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ShadowEntry

impl StructuralPartialEq for ShadowEntry
