ard/map

The ard/map module currently provides one helper for creating empty maps with Str keys.

It is available from the prelude as Map. You can also import ard/map when you want the lowercase module namespace explicitly:

use ard/map

API

new() [Str: $V]

Create a new empty map with Str keys and values of type $V. The value type is usually inferred from the assignment context, or named with an explicit type argument — let counts = mut Map::new<Int>() starts an empty mutable map without a binding annotation or import through the prelude alias.

use ard/map

let labels: [Str: Str] = map::new()
let counts: [Str: Int] = map::new()

This is equivalent to an empty map literal with an explicit type:

let labels: [Str: Str] = [:]
