Enum GroupKeyValue

pub enum GroupKeyValue {
    Int(i32),
    Str(String),
    Bool(bool),
}

表示分组键中的单个值

在 GroupBy 操作中用于构建分组键，支持常用的可哈希和可比较的数据类型。

支持的类型

• Int - 32位整数
• Str - 字符串
• Bool - 布尔值

示例

use axion::dataframe::types::GroupKeyValue;
 
let key1 = GroupKeyValue::Int(42);
let key2 = GroupKeyValue::Str("category".to_string());
let key3 = GroupKeyValue::Bool(true);

Variants

Int(i32)

Str(String)

Bool(bool)

Trait Implementations

impl Clone for GroupKeyValue

fn clone(&self) -> GroupKeyValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupKeyValue

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

Formats the value using the given formatter.

impl Hash for GroupKeyValue

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GroupKeyValue

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
