Module arrow::datatypes [−][src]
Expand description
Structs
Contains the meta-data for a single relative type.
Describes the meta-data of an ordered sequence of relative types.
Enums
The set of datatypes that are supported by this implementation of Apache Arrow.
YEAR_MONTH or DAY_TIME interval in SQL style.
An absolute length of time in seconds, milliseconds, microseconds or nanoseconds.
Traits
A subtype of primitive type that represents legal dictionary keys. See https://arrow.apache.org/docs/format/Columnar.html
Trait expressing a Rust type that has the same in-memory representation
as Arrow. This includes i16, f32, but excludes bool (which in arrow is represented in bits).
In little endian machines, types that implement ArrowNativeType can be memcopied to arrow buffers
as is.
Trait bridging the dynamic-typed nature of Arrow (via DataType) with the
static-typed nature of rust types (ArrowNativeType) for all types that implement ArrowNativeType.
A subtype of primitive type that represents temporal values.
A timestamp type allows us to create array builders that take a timestamp.
Trait declaring any type that is serializable to JSON. This includes all primitive types (bool, i32, etc.).
Allows conversion from supported Arrow types to a byte slice.
