pub fn default_q_range(out_kind: ElementKind) -> Option<(i32, i32)>Expand description
Default qmin / qmax for an output integer dtype. Today wired for
the two trailblazer output kinds — baracuda_kernels_types::S8
([-128, 127]) and baracuda_kernels_types::U8 ([0, 255]).
Returns None for unsupported kinds; the plan’s select() returns
Error::Unsupported in that case.
