pub enum LimitEffect {
None,
Unknown,
Relative(usize),
Absolute(usize),
}Expand description
the effect this function will have on the limit pushdown
Variants§
None
Does not affect the limit (i.e. this is causal)
Unknown
Either undeclared, or dynamic (only evaluatable at run time)
Relative(usize)
Grow the limit by N rows
Absolute(usize)
Limit needs to be at least N rows
