A Value in a Row, supporting all Spark SQL types.

Variants

Null

NULL value

Bool(bool)

Boolean

Byte(i8)

Byte (i8)

Short(i16)

Short (i16)

Integer(i32)

Integer (i32)

Long(i64)

Long (i64)

Float(f32)

Float (f32)

Double(f64)

Double (f64)

String(String)

String

Binary(Vec<u8>)

Binary (bytes)

Date(i32)

Date (days since epoch)

Timestamp(i64)

Timestamp (microseconds since epoch)

Decimal

Decimal (string value with optional precision and scale)

Fields

value: String

precision: Option<i32>

scale: Option<i32>

List(Vec<Value>)

Array of values

Map(BTreeMap<String, Value>)

Map of key-value pairs

Struct(Vec<(String, Value)>)

Struct (nested Row)

Variant

A VARIANT value carried as its raw (value, metadata) binary components, matching pyspark.sql.types.VariantVal(value, metadata). Decoding to JSON/Python is done lazily on the Python side (VariantVal.toJson/toPython via variant_utils).

Fields

value: Vec<u8>

metadata: Vec<u8>

Implementations

impl Value

pub fn as_bool(&self) -> Option<bool>

Get this value as a bool, or None if it’s not a bool.

pub fn as_i64(&self) -> Option<i64>

Get this value as i64, or None if it’s not an integer type.

pub fn as_f64(&self) -> Option<f64>

Get this value as f64, or None if it’s not a float type.

pub fn as_str(&self) -> Option<&str>

Get this value as a string reference, or None if it’s not a string.

pub fn as_bytes(&self) -> Option<&[u8]>

Get this value as a bytes reference, or None if it’s not binary.

pub fn is_null(&self) -> bool

Check if this value is null.
