std: Fix overflow of HashMap's capacity 2014-07-26 04:45:09 +01:00
refactor libcollections as part of collection reform * Moves multi-collection files into their own directory, and splits them into seperate files * Changes exports so that each collection has its own module * Adds underscores to public modules and filenames to match standard naming conventions (that is, treemap::{TreeMap, TreeSet} => tree_map::TreeMap, tree_set::TreeSet) * Renames PriorityQueue to BinaryHeap * Renames SmallIntMap to VecMap * Miscellanious fallout fixes [breaking-change] 2014-10-30 21:25:08 -04:00			`use std::collections::hash_map::HashMap;`
