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 DefId
s.

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.
