Function vnode

source
pub fn vnode(range: &TableKeyRange) -> VirtualNode
Expand description

Ensure there is only one vnode involved in table key range and return the vnode.

ยงVnode count unawareness

Note that this function is not aware of the vnode count that is actually used in this table. For example, if the total vnode count is 256, Unbounded can be a correct end bound for vnode 255, but this function will still require Excluded(256).

See also vnode_range and end_bound_of_vnode which hold such invariant.
