Function scylla::transport::partitioner::calculate_token_for_partition_key

pub fn calculate_token_for_partition_key<P: Partitioner>(
    serialized_partition_key_values: &SerializedValues,
    partitioner: &P,
) -> Result<Token, TokenCalculationError>

Calculates the token for given partitioner and serialized partition key.

The ordinary way to calculate token is based on a PreparedStatement and values for that statement. However, if a user knows:

• the order of the columns in the partition key,
• the values of the columns of the partition key,
• the partitioner of the table that the statement operates on,

then having a PreparedStatement is not necessary and the token can be calculated based on that information.

NOTE: the provided values must completely constitute partition key and be in the order defined in CREATE TABLE statement.
