Enum gcp_client::google::bigtable::v2::read_modify_write_rule::Rule

pub enum Rule {
    AppendValue(Vec<u8>),
    IncrementAmount(i64),
}

The rule used to determine the column's new latest value from its current latest value.

Variants

AppendValue(Vec<u8>)

Rule specifying that append_value be appended to the existing value. If the targeted cell is unset, it will be treated as containing the empty string.

IncrementAmount(i64)

Rule specifying that increment_amount be added to the existing value. If the targeted cell is unset, it will be treated as containing a zero. Otherwise, the targeted cell must contain an 8-byte value (interpreted as a 64-bit big-endian signed integer), or the entire request will fail.
