Function erased_map_into 

pub fn erased_map_into(
    input_dtype: KernelDType,
    op: ErasedMapOp,
    ctx: &ExecContext,
    dest: &mut ErasedRawStridedMut<'_>,
    input: &ErasedRawStridedPtr<'_>,
) -> Result<()>

Apply one runtime-selected unary operation without compiling a plan.

The destination must not overlap the input. Real and complex dtypes support every ErasedMapOp, signed integers use wrapping negate/abs semantics, and bool supports only ErasedMapOp::Conj. Complex absolute value has the real output contract c32 -> f32 and c64 -> f64; all other supported unary operations preserve dtype.

Errors

Returns a typed StridedError for dtype, shape, output-layout, overlap, or unsupported dtype/op contracts. Validation completes before any write.
