pub struct Cohort {
    pub id: Option<String>,
    pub hint: Option<String>,
    pub name: Option<String>,
}
Expand description

The cohort identifies the update ‘track’ or ‘channel’, and is used to implement the tracking of membership in a fractional roll-out. This is per-application data.

This is sent to Omaha to identify the cohort that the application is in. This is returned (with possibly new values) by Omaha to indicate that the application is now in a different cohort. On the next update check for that application, the updater needs to use this newly returned cohort as the one that it sends to Omaha with that application.

For more information about cohorts, see the ‘cohort’, ‘cohorthint’, and ‘cohortname’ attributes of the Request.App object at:

https://github.com/google/omaha/blob/HEAD/doc/ServerProtocolV3.md#app-request

Fields§

§id: Option<String>

This is the cohort id itself.

§hint: Option<String>§name: Option<String>
