Struct melior::dialect::ods::pdl_interp::GetResultsOperation

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

A get_results operation. Get a specified result group from an Operation.

pdl_interp.get_results operations try to get a specific result group from an operation. If the expected result is a single Value, null is returned if the result group is not of size 1. If a range is expected, null is returned if the result group is invalid. If no index is provided, the returned operand group corresponds to all results of the operation.

Example:

// Get the first group of results from an operation, and expect a single
// element.
%result = pdl_interp.get_results 0 of %op : !pdl.value

// Get the first group of results from an operation.
%results = pdl_interp.get_results 0 of %op : !pdl.range<value>

// Get all of the results from an operation.
%results = pdl_interp.get_results of %op : !pdl.range<value>
