Struct PoolSpec 

pub struct PoolSpec {
    pub kind: u8,
    pub key_capacity: usize,
    pub lane_capacity: usize,
}

Which segment a Pool uses, and how big it is.

One fleet can hold several independent pools: an upstream’s origins and an outbound client’s targets share neither a budget, a key space nor an epoch, so each names its own kind. A kind is a fleet-wide identity — every process opening it must pass the same capacities, and the segment’s header refuses a peer that does not. PoolSpec::DEFAULT is what Pool::new opens; its values are the compile-time geometry.

Fields

kind: u8

The Orbit SHM kind, and with it the segment name.

key_capacity: usize

Distinct keys this pool can name at once. A power of two.

lane_capacity: usize

Resources one fleet node can register at once. A power of two, at most 65 536.
