[−][src]Enum arrow::datatypes::DataType
The possible relative types that are supported.
The variants of this enum include primitive fixed size types as well as parametric or nested types. Currently the Rust implementation supports the following nested types:
List<T>
Struct<T, U, V, ...>
Nested types can themselves be nested within other arrays. For more information on these types please see here.
