Crate rustc_abi

Modules

• layout 🔒

Structs

• AbiAndPrefAlign
  A pair of alignments, ABI-mandated and preferred.
• AddressSpace
  An identifier that specifies the address space that some operation should operate on. Special address spaces have an effect on code generation, depending on the target and the address spaces it implements.
• Align
  Alignment of a type in bytes (always a power of two).
• LayoutS
• Niche
• PointeeInfo
  Note that this information is advisory only, and backends are free to ignore it. It can only be used to encode potential optimizations, but no critical information.
• ReprFlags
• ReprOptions
  Represents the repr options provided by the user.
• Size
  Size of a type in bytes.
• TargetDataLayout
  Parsed Data layout for a target, which contains everything needed to compute layouts.
• WrappingRange
  Inclusive wrap-around range of valid values, that is, if start > end, it represents start..=MAX, followed by 0..=end.

Enums

• Abi
  Describes how values of the type are passed by target ABIs, in terms of categories of C types there are ABI rules for.
• AlignFromBytesError
• Endian
  Endianness of the target, which must match cfg(target-endian).
• FieldsShape
  Describes how the fields of a type are located in memory.
• Integer
  Integers, also used for enum discriminants.
• IntegerType
• PointerKind
• Primitive
  Fundamental unit of memory access and layout.
• Scalar
  Information about one scalar component of a Rust type.
• StructKind
• TagEncoding
• TargetDataLayoutErrors
• Variants

Traits

• HasDataLayout
• HashStableContext
  Requirements for a StableHashingContext to be used in this crate. This is a hack to allow using the HashStable_Generic derive macro instead of implementing everything in rustc_middle.
• LayoutCalculator
