Constants
The maximum precision for DataType::Decimal128 values
The maximum scale for DataType::Decimal128 values
The maximum precision for DataType::Decimal256 values
The maximum scale for DataType::Decimal256 values
The default scale for DataType::Decimal128 and DataType::Decimal256
values
MAX_DECIMAL_FOR_EACH_PRECISION[p] holds the maximum i128 value that can
be stored in arrow_schema::DataType::Decimal128 value of precision pMIN_DECIMAL_FOR_EACH_PRECISION[p] holds the minimum i128 value that can
be stored in a arrow_schema::DataType::Decimal128 value of precision pTraits
A subtype of primitive type that represents legal dictionary keys.
See https://arrow.apache.org/docs/format/Columnar.html
A subtype of primitive type that represents numeric float values
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).Trait for
ArrowNativeType that adds checked and unchecked arithmetic operations,
and totally ordered comparison operationsA subtype of primitive type that represents numeric values.
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.
A trait over the variable-size byte array types
A trait over the decimal types, used by
PrimitiveArray to provide a generic
implementation across the various decimal typesAllows conversion from supported Arrow types to a byte slice.
