Struct rustc_hir::definitions::DisambiguatedDefPathData

source ·
pub struct DisambiguatedDefPathData {
    pub data: DefPathData,
    pub disambiguator: u32,
}
Expand description

A pair of DefPathData and an integer disambiguator. The integer is normally 0, but in the event that there are multiple defs with the same parent and data, we use this field to disambiguate between them. This introduces some artificial ordering dependency but means that if you have, e.g., two impls for the same type in the same module, they do get distinct DefIds.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
