Struct FlowMap

pub struct FlowMap { /* private fields */ }

Storage for flows

A Flow is identified by a FlowID. Multiple FlowID may point to the same flow (direct and reverse flow, for ex.).

Implementations

impl FlowMap

pub fn with_rng_seed(self, seed: u64) -> Self

Use provided seed for the random number generator (flow IDs)

This option is intended for use in testing

pub fn lookup_flow(&self, five_t: &FiveTuple) -> Option<FlowID>

pub fn len(&self) -> usize

Return the number of flows

pub fn is_empty(&self) -> bool

Returns true if the map contains no elements.

pub fn insert_flow(&mut self, five_t: FiveTuple, flow: Flow) -> FlowID

Insert a flow in the hash tables. Takes ownership of five_t and flow

pub fn get_flow(&self, flow_id: FlowID) -> Option<&Flow>

Return a reference to the flow identified by flow_id

pub fn get_flow_mut(&mut self, flow_id: FlowID) -> Option<&mut Flow>

Return a mutable reference to the flow identified by flow_id

pub fn values(&self) -> Values<'_, FlowID, Flow>

An iterator visiting all flows in arbitrary order.

pub fn entry(&mut self, flow_id: FlowID) -> Entry<'_, FlowID, Flow>

Gets the given key’s corresponding entry in the map for in-place manipulation.

pub fn clear(&mut self)

Remove all flows

Trait Implementations

impl Default for FlowMap

fn default() -> Self

Returns the “default value” for a type.
