# `cassandra.encoder` - Encoders for non-prepared Statements

class `cassandra.encoder.``Encoder`

  A container for mapping python types to CQL string literals when working with non-prepared statements. The type `mapping` can be directly customized by users.

  `mapping` = None

    A map of python types to encoder functions.

  `cql_encode_none`()

    Converts `None` to the string ‘NULL’.

  `cql_encode_object`()

    Default encoder for all objects that do not have a specific encoder function registered. This function simply calls `str()` on the object.

  `cql_encode_all_types`()

    Converts any type into a CQL string, defaulting to `cql_encode_object` if `mapping` does not contain an entry for the type.

  `cql_encode_sequence`()

    Converts a sequence to a string of the form `(item1, item2, ...)`. This is suitable for `IN` value lists.

  `cql_encode_str`()

    Escapes quotes in `str` objects.

  `cql_encode_unicode`()

    Converts `unicode` objects to UTF-8 encoded strings with quote escaping.

  `cql_encode_bytes`()

    Converts strings, buffers, and bytearrays into CQL blob literals.

  `cql_encode_datetime`()

    Converts a `datetime.datetime` object to a (string) integer timestamp with millisecond precision.

  `cql_encode_date`()

    Converts a `datetime.date` object to a string with format `YYYY-MM-DD`.

  `cql_encode_map_collection`()

    Converts a dict into a string of the form `{key1: val1, key2: val2, ...}`. This is suitable for `map` type columns.

  `cql_encode_list_collection`()

    Converts a sequence to a string of the form `[item1, item2, ...]`. This is suitable for `list` type columns.

  `cql_encode_set_collection`()

    Converts a sequence to a string of the form `{item1, item2, ...}`. This is suitable for `set` type columns.

  `cql_encode_tuple`()

    Converts a sequence to a string of the form `(item1, item2, ...)`. This is suitable for `tuple` type columns.
