Skip to main content Module abi Copy item path Source 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. ArgAbi Information about the ABI of a function’s argument, or return value. ArgAttributes Attributes of a function argument that affect its ABI. CastTarget Describes the ABI type that an argument is transmuted to for PassMode::Cast. FnAbi A function ABI definition. Layout LayoutShape The layout of a type, including its size, alignment, field offsets, and backend representation. NumScalableVectors The number of scalable vectors in a ValueRepr::ScalableVector Reg A register type used in ABI calling conventions. ReprFlags ReprOptions Representation options provided by the user TyAndLayout The layout of a type, alongside the type itself. Uniform A sequence of registers of the same kind used to pass an argument. VariantFields WrappingRange Inclusive wrap-around range of valid values (bitwise representation), that is, if
start > end, it represents start..=MAX, followed by 0..=end. ArgExtension How a small integer argument should be extended to fill a register. CallConvention General language calling conventions. FieldsShape Describes the number and position of fields within a type’s layout. FloatLength Enum representing the existing float lengths. IntegerLength Enum representing the existing integer lengths. IntegerType PassMode How a function argument should be passed in to the target function. Primitive A primitive scalar type: integer, float, or pointer. RegKind The kind of a register used in calling conventions. Scalar Information about one scalar component of a Rust type. TagEncoding ValueRepr A hint for how backends should represent values of this type. VariantsShape
