RubyGems.org Adds New Maintainer Role
RubyGems.org has added a new "maintainer" role that allows for publishing new versions of gems. This new permission type is aimed at improving security for gem owners and the service overall.
@rimbu/hashed
Advanced tools
This package contains the implementation for the HashMap
and HashSet
types, which form the basis of all Rimbu Hashed collections. The collections use a Hasher
instance that is configurable to determine the equality of values/objects.
This package exports the following main types:
Name | Description |
---|---|
HashMap<K, V> | a map with entries of key type K and value type V, where keys are hashed with a Hasher |
HashSet<T> | a set of value type T where items are hashed with a Hasher |
For complete documentation please visit the Map or Set page Rimbu Docs, or directly see the Rimbu Hashed API Docs.
Or Try Out Rimbu in CodeSandBox.
For convenience, all main types are also exported through @rimbu/core
.
To install separately:
yarn add @rimbu/hashed
or
npm i @rimbu/hashed
For Deno, the following approach is recommended:
In the root folder of your project, create or edit a file called import_map.json
with the following contents (where you should replace x.y.z
with the desired version of Rimbu):
{
"imports": {
"@rimbu/": "https://deno.land/x/rimbu@x.y.z/"
}
}
Note: The trailing slashes are important!
In this way you can use relative imports from Rimbu in your code, like so:
import { List } from '@rimbu/core/mod.ts';
import { HashMap } from '@rimbu/hashed/mod.ts';
Note that for sub-packages, due to conversion limitations it is needed to import the index.ts
instead of mod.ts
, like so:
import { HashMap } from '@rimbu/hashed/map/index.ts';
To run your script (let's assume the entry point is in src/main.ts
):
deno run --import-map import_map.json src/main.ts
Because Rimbu uses advanced types, this may slow down the type checking part when running your code. If you're able to rely on your code editor to provide type errors, you can skip the Deno type check using the --no-check
flag:
deno run --import-map import_map.json --no-check src/main.ts
import { HashSet } from '@rimbu/hashed';
console.log(HashSet.of(1, 3, 2, 4, 3, 1).toString());
