Enum ValueRepr 

pub enum ValueRepr {
    Scalar(Scalar),
    ScalarPair {
        a: Scalar,
        b: Scalar,
        b_offset: MachineSize,
    },
    Vector {
        element: Scalar,

    },
    Aggregate {
        sized: bool,
    },
}

A hint for how backends should represent values of this type.

Distinguishes between types representable as scalars, pairs of scalars, SIMD vectors, or aggregates.

Variants

Scalar(Scalar)

ScalarPair

Fields

a: Scalar

b: Scalar

b_offset: MachineSize

Vector

A fixed-length SIMD vector.

Fields

element: Scalar

count: u64

ScalableVector

A scalable SIMD vector (e.g., ARM SVE).

Fields

element: Scalar

count: u64

number_of_vectors: NumScalableVectors

Aggregate

The type is not representable as a scalar or vector (e.g., aggregates, unsized types).

Fields

sized: bool

If true, the size is exact, otherwise it’s only a lower bound.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
