Struct CastSubByteDescriptor 

pub struct CastSubByteDescriptor {
    pub numel: i32,
    pub input_element: ElementKind,
    pub output_element: ElementKind,
}

Descriptor for a sub-byte cast.

numel is the element count for both input and output (cast doesn’t change shape). For S4 / U4 endpoints numel MUST be even — the packed buffer is numel / 2 bytes, and odd numels would leave a dangling half-byte.

input_element and output_element are the runtime dtype tags; they must match TIn / TOut’s underlying width (the plan cross-checks via sizeof::<T>() at select time).

Fields

numel: i32

Number of elements in both input and output.

input_element: ElementKind

Input element type.

output_element: ElementKind

Output element type.
