Struct cassandra_cpp::TimestampGen

pub struct TimestampGen(_);

Generators of client-side, microsecond-precision timestamps. Note: This generator is thread-safe and can be shared by multiple sessions.

Methods

impl TimestampGen

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).

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.

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.
