any_set_expr()

template<typename ExprFn , typename FirstBitSpanT , typename... BitSpanT>

bool blender::bits::detail::any_set_expr ( ExprFn && expr, const FirstBitSpanT & first_arg, const BitSpanT &... args )

inline

Evaluates the expression on one or more bit spans and returns true when the result contains a 1 anywhere.

The expected type for the expression is: (BitInt ...one_or_more_args) -> BitInt

foreach_1_index_expr()

template<typename ExprFn , typename HandleFn , typename FirstBitSpanT , typename... BitSpanT>

void blender::bits::detail::foreach_1_index_expr ( ExprFn && expr, HandleFn && handle, const FirstBitSpanT & first_arg, const BitSpanT &... args )

inline

Evaluates the expression on one or more bit spans and calls the handle function for each bit index where the result is 1.

The expected type for the expression is: (BitInt ...one_or_more_args) -> BitInt

mix_into_first_expr()

template<typename ExprFn , typename FirstBitSpanT , typename... BitSpanT>

void blender::bits::detail::mix_into_first_expr ( ExprFn && expr, const FirstBitSpanT & first_arg, const BitSpanT &... args )

inline

Evaluates the expression on one or more bit spans and stores the result in the first.

The expected type for the expression is: (BitInt ...one_or_more_args) -> BitInt
