Struct RootData

pub struct RootData {
    next: u16,
    keys: BTreeMap<u16, RangeData>,
}

Fields

next: u16

Next port to try.

keys: BTreeMap<u16, RangeData>

Map of port ranges. For each range, the key is the first port in the range and the range size and expiration time are stored in the value.

Implementations

impl RootData

pub fn get_free_port_range(&mut self, range_size: u16) -> u16

fn reclaim(&mut self)

Remove expired entries from the map.

fn contains(&self, range: Range<u16>) -> Option<u16>

Check if range conflicts with anything already reserved

If it does return next address after the range that conflicted.

fn insert(&mut self, range: Range<u16>)

fn now_ts() -> u64
