Struct UsyncDeviceSyncHint 

#[non_exhaustive]
pub struct UsyncDeviceSyncHint {
    pub device_hash: Option<CompactString>,
    pub timestamp: Option<i64>,
    pub expected_timestamp: Option<i64>,
}

Per-user cache hints carried by the devices v2 subprotocol.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

device_hash: Option<CompactString>

Cached device-list hash, if known.

timestamp: Option<i64>

Timestamp associated with the cached hash.

expected_timestamp: Option<i64>

Expected timestamp used to detect stale key-index state.

Implementations

impl UsyncDeviceSyncHint

pub const fn new() -> UsyncDeviceSyncHint

Construct an empty hint.

pub fn with_device_hash( self, device_hash: impl Into<CompactString>, ) -> UsyncDeviceSyncHint

Attach a cached device-list hash.

pub const fn with_timestamp(self, timestamp: i64) -> UsyncDeviceSyncHint

Attach the cached device-list timestamp.

pub const fn with_expected_timestamp( self, expected_timestamp: i64, ) -> UsyncDeviceSyncHint

Attach the expected key-index timestamp.

pub fn is_empty(&self) -> bool

Whether this hint contributes no wire attributes.
