API docs

Usage

Use queryst library to parse query-string to corresponding [json values].

```rust use queryst::parse;

// will contain result as Json value let object = parse("foo[0][a]=a&foo[0][b]=b&foo[1][a]=aa&foo[1][b]=bb"); ```

Description

queryst allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets []. or example, the string 'foo[bar]=baz' converts to this JSON:

json { "foo": { "bar": "baz" } }

URI encoded strings work too:

js parse('a%5Bb%5D=c'); // { "a": { "b": "c" } }

You can also nest your objects, like 'foo[bar][baz]=foobarbaz':

javascript { "foo": { "bar": { "baz": "foobarbaz" } } }

Parsing Arrays

queryst can also parse arrays using a similar [] notation:

javascript parse('a[]=b&a[]=c'); // { "a": ["b", "c"] }

You may specify an index as well:

javascript parse('a[0]=c&a[1]=b'); // { "a": ["c", "b"] }

Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number to create an array.

queryst does't allow to specify sparse indexes on arrays and will convert target array to object:

javascript parse('a[1]=b&a[15]=c'); // { "a": {"1": "b", "15": "c"} }

Also if you mix notations, queryst will merge the two items into an object:

javascript parse('a[0]=b&a[b]=c'); // { "a": { "0": "b", "b": "c" } }

You can also create arrays of objects:

javascript parse('a[][b]=c'); // { "a": [{ "b": "c" }] }
