Struct cassandra_cpp::TimestampGen
source · pub struct TimestampGen(_);
Expand description
Generators of client-side, microsecond-precision timestamps. Note: This generator is thread-safe and can be shared by multiple sessions.
Implementations§
source§impl TimestampGen
impl TimestampGen
sourcepub fn time_from_epoch(epoch_seconds: Duration) -> Time
pub fn time_from_epoch(epoch_seconds: Duration) -> Time
Converts a unix timestamp (in seconds) to the Cassandra “time” type. The “time” type represents the number of nanoseconds since midnight (range 0 to 86399999999999).
sourcepub fn gen_monotonic_new() -> Self
pub fn gen_monotonic_new() -> Self
Creates a new monotonically increasing timestamp generator. This generates microsecond timestamps with the sub-millisecond part generated using a counter. The implementation guarantees that no more than 1000 timestamps will be generated for a given clock tick even if shared by multiple session objects. If that rate is exceeded then a warning is logged and timestamps stop incrementing until the next clock tick.
sourcepub fn gen_server_side_new() -> Self
pub fn gen_server_side_new() -> Self
Creates a new server-side timestamp generator. This generator allows Cassandra to assign timestamps server-side.
Note: This is the default timestamp generator.
