Struct GlobalRequirements 

pub struct GlobalRequirements {
    fetch: Option<usize>,
    skip: usize,
    satisfied: bool,
}

This is a “data class” we use within the LimitPushdown rule to push down LimitExec in the plan. GlobalRequirements are hold as a rule-wide state and holds the fetch and skip information. The struct also has a field named satisfied which means if the “current” plan is valid in terms of limits or not.

For example: If the plan is satisfied with current fetch info, we decide to not add a LocalLimit

Fields

fetch: Option<usize>

skip: usize

satisfied: bool
