Struct rustc_symbol_mangling::v0::BinderLevel

struct BinderLevel {
    lifetime_depths: Range<u32>,
}

Fields

lifetime_depths: Range<u32>

The range of distances from the root of what’s being printed, to the lifetimes in a binder. Specifically, a BrAnon(i) lifetime has depth lifetime_depths.start + i, going away from the the root and towards its use site, as i increases. This is used to flatten rustc’s pairing of BrAnon (intra-binder disambiguation) with a DebruijnIndex (binder addressing), to “true” de Bruijn indices, by subtracting the depth of a certain lifetime, from the innermost depth at its use site.

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.
