Function get_operand

Source 
pub fn get_operand(val: &ValueRef, index: u32) -> Option<ValueRef>
Expand description

Obtain an operand at a specific index in a LLVM User value.

§Details

Retrieves an operand at a specified index from a value in LLVM IR.

This function wraps the LLVMGetOperand function from the LLVM core library. It returns the operand at the specified index (index) from the value represented by ValueRef. Operands are the inputs to instructions or other values in LLVM IR. If the index is out of bounds or the operand cannot be retrieved, the function returns None.

§Parameters

  • index: The index of the operand to retrieve. This index should be within the bounds of the number of operands the value has.

§Returns

Returns an Option<ValueRef>:

  • Some(ValueRef) containing the retrieved operand if the index is valid and the operand is found.
  • None if the index is out of bounds or the operand cannot be retrieved.
