Enum arrow::datatypes::DataType

pub enum DataType {
    Boolean,
    Int8,
    Int16,

    Int64,
    UInt8,

    Struct(Vec<Field>),
}

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.

Methods

impl DataType

pub fn to_json(&self) -> Value

Generate a JSON representation of the data type

Trait Implementations

impl Eq for DataType

impl PartialEq<DataType> for DataType

fn eq(&self, other: &DataType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DataType) -> bool

This method tests for !=.

impl Clone for DataType

fn clone(&self) -> DataType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataType

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for DataType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl<'de> Deserialize<'de> for DataType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where     __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for DataType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where     __S: Serializer,

Serialize this value into the given Serde serializer.
