Struct RrfConfig 

pub struct RrfConfig {
    pub k: u32,
    pub top_k: Option<usize>,
}

RRF configuration.

Example

use rankops::RrfConfig;

let config = RrfConfig::default()
    .with_k(60)
    .with_top_k(10);

Fields

k: u32

Smoothing constant (default: 60).

Must be >= 1 to avoid division by zero in the RRF formula. Values < 1 will cause panics during fusion.

top_k: Option<usize>

Maximum results to return (None = all).

Implementations

impl RrfConfig

pub fn new(k: u32) -> Self

Create config with custom k.

Panics

Panics if k == 0 (would cause division by zero in RRF formula).

Example

use rankops::RrfConfig;

let config = RrfConfig::new(60);

pub fn with_k(self, k: u32) -> Self

Set the k parameter (smoothing constant).

• k=60 — Standard RRF, works well for most cases
• k=1 — Top positions dominate heavily
• k=100+ — More uniform contribution across ranks

Panics

Panics if k == 0 (would cause division by zero in RRF formula).

pub const fn with_top_k(self, top_k: usize) -> Self

Limit output to top_k results.

Trait Implementations

impl Clone for RrfConfig

fn clone(&self) -> RrfConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RrfConfig

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

Formats the value using the given formatter.

impl Default for RrfConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RrfConfig

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