StashTable

Concurrent hash table for Nim. Excellent way to safely share arbitrary data between multiple threads.

Example

# nim r example.nim
import os, random, stashtable

type SharedData = StashTable[string, seq[string], 100]

proc threading(d: tuple[t: int, shareddata: SharedData]) =
  for i in 0 .. 10:
    sleep(rand(10))
    d.shareddata.withValue("somekey"): value[].add($d.t & "->" & $i)

let shareddata = newStashTable[string, seq[string], 100]()
shareddata.insert("somekey", @[])

var threads: array[2, Thread[tuple[t: int, shareddata: SharedData]]]
for i in 0 .. 1: createThread(threads[i], threading, (i, shareddata))
joinThreads(threads)
echo shareddata
