Struct TournamentTree

Source

pub struct TournamentTree { /* private fields */ }

Expand description

Tournament tree for efficient k-way merge

Uses a complete binary tree where each internal node contains the “winner” of comparing its two children.

Implementations§

Source §

impl TournamentTree

Source

pub fn new(num_sources: usize) -> Self

Create a new tournament tree

Source

pub fn initialize(&mut self, sources: &[Box<dyn EntrySource>])

Initialize tree with current entries from sources

Source

pub fn peek(&self) -> Option<&VersionedEntry>

Get the current winner (minimum key)

Source

pub fn winner_source(&self) -> Option<u32>

Get the source index of the current winner

Source

pub fn pop( &mut self, sources: &mut [Box<dyn EntrySource>], ) -> Option<VersionedEntry>

Advance the winning source and rebuild the tree
