Module abi

Re-exports

• pub use crate::callconv as call;

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).
• FieldIdx
  The source-order index of a field in a variant.
• Heterogeneous
  Error from the homogeneous_aggregate test function, indicating there are distinct leaf fields passed in different ways, or this is uninhabited.
• Layout
• LayoutCalculator
• LayoutData
• 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.
• Reg
• 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.
• TyAndLayout
  The layout of a type, alongside the type itself. Provides various type traversal APIs (e.g., recursing into fields).
• VariantIdx
  The source-order index of a variant in a type.
• 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.
• Float
  Floating-point types.
• HomogeneousAggregate
  Return value from the homogeneous_aggregate test function.
• Integer
  Integers, also used for enum discriminants.
• IntegerType
• LayoutCalculatorError
• PointerKind
• Primitive
  Fundamental unit of memory access and layout.
• RegKind
• Scalar
  Information about one scalar component of a Rust type.
• StructKind
• TagEncoding
• TargetDataLayoutErrors
• Variants

Constants

• FIRST_VARIANT
  Equivalent to VariantIdx(0).

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.
• TyAbiInterface
  Trait that needs to be implemented by the higher-level type representation (e.g. rustc_middle::ty::Ty), to provide rustc_target::abi functionality.
