Enum DynVolume 

#[non_exhaustive]
pub enum DynVolume {
    U8(Volume<u8>),
    I8(Volume<i8>),
    U16(Volume<u16>),
    I16(Volume<i16>),
    U32(Volume<u32>),
    I32(Volume<i32>),
    F32(Volume<f32>),
    F64(Volume<f64>),
}

A volume whose scalar type is determined at runtime.

This enum lets a consumer store any supported scalar flavour behind one handle without carrying T as a generic parameter.

VTK Equivalent

vtkImageData::GetScalarType() — a runtime tag rather than a compile-time type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

U8(Volume<u8>)

Unsigned 8-bit integer voxels.

I8(Volume<i8>)

Signed 8-bit integer voxels.

U16(Volume<u16>)

Unsigned 16-bit integer voxels.

I16(Volume<i16>)

Signed 16-bit integer voxels (most common for CT Hounsfield units).

U32(Volume<u32>)

Unsigned 32-bit integer voxels.

I32(Volume<i32>)

Signed 32-bit integer voxels.

F32(Volume<f32>)

32-bit floating-point voxels.

F64(Volume<f64>)

64-bit floating-point voxels.

Implementations
