Partial-Element Setter

This function inserts a portion of an integer value into a PartialElement. The BitField implementations call it as they disassemble a complete integer. It performs the following steps:

1. the value is resized into a T::Mem,
2. shifted up from LSedge as needed to fit in the governed region of the partial element,
3. and then stored (after masking away excess bits) through the PartialElement into memory.

Type Parameters

• O and T are the type parameters of the PartialElement argument.
• U is the source integer type.

Parameters

• elem: A PartialElement into which a value segment will be written.
• value: A value, whose least-significant bits will be written into elem.
• shamt: The shift distance from the storage location’s LSedge to its live bits.
