[−][src]Struct rustc::ty::layout::TyLayout
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
The details of the layout of a type, alongside the type itself. Provides various type traversal APIs (e.g. recursing into fields).
Note that the details are NOT guaranteed to always be identical
to those obtained from layout_of(ty)
, as we need to produce
layouts for which Rust types do not exist, such as enum variants
or synthetic fields of enums (i.e. discriminants) and fat pointers.
