Struct routing::MessageId

pub struct MessageId(_);

Unique ID for messages

This is used for deduplication: Since the network sends messages redundantly along different routes, the same message will usually arrive more than once at any given node. A message with an ID that is already in the cache will be ignored.

Methods

impl MessageId

fn new() -> MessageId

Generate a new MessageId with random content.

fn zero() -> MessageId

Generate a MessageId with value 0. This should only be used for messages where there is no danger of duplication.

fn from_lost_node(name: XorName) -> MessageId

Generate a new MessageId with contents extracted from lost node.

fn from_added_node(name: XorName) -> MessageId

Generate a new MessageId with contents extracted from new node.

fn from_reverse(name: &MessageId) -> MessageId

Generate the reverse of the given MessageId.

fn increment_first_byte(message_id: &MessageId) -> MessageId

Generate the increment (on the MSB only) of the given MessageId.

fn decrement_first_byte(message_id: &MessageId) -> MessageId

Generate the decrement (on the MSB only) of the given MessageId.
