Struct sql_ops::partition::Tuple

source · [−]

#[repr(C)]
pub struct Tuple<Key: Sized, Value: Sized> {
    pub key: Key,
    pub value: Value,
}

Expand description

A key-value tuple.

The partitioned relation is stored as a collection of Tuple<K, V>.

Note that the struct’s layout must be kept in sync with its counterpart in C/C++.
