Struct NodeKey 

pub struct NodeKey {
    pub file: FileId,
    pub range: (u32, u32),
}

Identity of one HIR node for side-table purposes: the file it lives in plus its source range.

TextRange has no Ord impl (ranges have no single natural total order), so the range travels as a (start, end) u32 pair — the same range_key convention infer, strict, and structs each already use for their own range-keyed maps. A range is only unique within a file, hence the FileId half: side-table entries must never be merged across files.

Fields

file: FileId

The file the node was lowered from.

range: (u32, u32)

The node’s source range, as (start, end).

Implementations

impl NodeKey

pub fn new(file: FileId, range: TextRange) -> Self
