Struct melior::dialect::ods::quant::QuantizeCastOperation

pub struct QuantizeCastOperation<'c> { /* private fields */ }

A qcast operation. Convert a quantizable type to a quantized type.

A QuantizeCast qcast represents a potential type shift from a quantizable type to a quantized type.

At runtime, a qcast will apply the transformation expressed by its operand and result type. For flexibility during transformation, it is also possible to have a qcast that performs no transformation (both its operand and result type are quantizable).

A qcast will typically originate from either: a) An expressed or implied constraint in the source dialect which signals that a certain level of quantization is possible or required. b) An inference made by a quantization algorithm indicating that a quantized representation may be acceptable.

Especially early in transformation, it is common to have pairs of qcast and dcast at points where a transition to a quantized type is required. In addition, it is also common to have an identity qcast (where the operand and result type are not quantized) at all points where it is legal to use a quantized representation (but is not known to be acceptable).
