Module rustc::ty::layout[−][src]

🔬 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?

call	[ Experimental ]

Align	[ Experimental ] Alignment of a type in bytes, both ABI-mandated and preferred. Each field is a power of two, giving the alignment a maximum value of 2^{(2⁸ - 1)}, which is limited by LLVM to a maximum capacity of 2²⁹ or 536870912.
LayoutCx	[ Experimental ]
LayoutDetails	[ Experimental ]
Niche	[ Experimental ]
Scalar	[ Experimental ] Information about one scalar component of a Rust type.
Size	[ Experimental ] Size of a type in bytes.
TargetDataLayout	[ Experimental ] Parsed Data layout for a target, which contains everything needed to compute layouts.
TyLayout	[ Experimental ] The details of the layout of a type, alongside the type itself. Provides various type traversal APIs (e.g. recursing into fields).

Abi	[ Experimental ] Describes how values of the type are passed by target ABIs, in terms of categories of C types there are ABI rules for.
Endian	[ Experimental ] Endianness of the target, which must match cfg(target-endian).
FieldPlacement	[ Experimental ] Describes how the fields of a type are located in memory.
FloatTy	[ Experimental ]
Integer	[ Experimental ] Integers, also used for enum discriminants.
LayoutError	[ Experimental ]
Primitive	[ Experimental ] Fundamental unit of memory access and layout.
SizeSkeleton	[ Experimental ] Type size "skeleton", i.e. the only information determining a type's size. While this is conservative, (aside from constant sizes, only pointers, newtypes thereof and null pointer optimized enums are allowed), it is enough to statically check common usecases of transmute.
Variants	[ Experimental ]

FAT_PTR_ADDR	[ Experimental ] The first half of a fat pointer.
FAT_PTR_EXTRA	[ Experimental ] The second half of a fat pointer.
