Enum Type

Source
pub enum Type {
    BOOLEAN,
    INT32,
    INT64,
    INT96,
    FLOAT,
    DOUBLE,
    BYTE_ARRAY,
    FIXED_LEN_BYTE_ARRAY,
}
Expand description

Types supported by Parquet. These physical types are intended to be used in combination with the encodings to control the on disk storage format. For example INT16 is not included as a type since a good encoding of INT32 would handle this.
