Struct dittolive_ditto::transport::Global

pub struct Global {
    pub sync_group: u32,
}

Settings not associated with any specific type of transport.

Fields

sync_group: u32

The sync group for this device.

When peer-to-peer transports are enabled, all devices with the same App ID will normally form an interconnected mesh network. In some situations it may be desirable to have distinct groups of devices within the same app, so that connections will only be formed within each group. The sync_group parameter changes that group membership. A device can only ever be in one sync group, which by default is group 0. Up to 2^32 distinct group numbers can be used in an app.

This is an optimization, not a security control. If a connection is created manually, such as by specifying a connect transport, then devices from different sync groups will still sync as normal. If two groups of devices are intended to have access to different data sets, this must be enforced using Ditto’s permissions system.
