Enum GpuHashStrategy 

pub enum GpuHashStrategy {
    Linear,
    Cuckoo,
    RobinHood,
}

GPU Hash Strategy for GROUP BY operations

Variants

Linear

Linear probing - best for small group counts (< 100)

Cuckoo

Cuckoo hashing - best for medium group counts (100-1000)

RobinHood

Robin Hood hashing - best for large group counts (> 1000) or large datasets

Implementations

impl GpuHashStrategy

pub fn parse(s: &str) -> DbxResult<Self>

Parse from string (case-insensitive)

pub fn as_str(&self) -> &'static str

Get strategy name

Trait Implementations

impl Clone for GpuHashStrategy

fn clone(&self) -> GpuHashStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuHashStrategy

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

Formats the value using the given formatter.

impl Default for GpuHashStrategy

fn default() -> GpuHashStrategy

Returns the “default value” for a type.

impl PartialEq for GpuHashStrategy

fn eq(&self, other: &GpuHashStrategy) -> 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.
