Serde-querystring

A query string parser for rust with support for different parsing methods.

Install

```toml

Cargo.toml

[dependencies] serde-querystring = "0.1.0" ```

Usage

You can use the parsers provided in this crate directly, examples are available in each parser's tests.

rust let parsed = DuplicateQS::parse(b"foo=bar&foo=baz"); let values = parser.values(b"foo"); // Will give you a vector of b"bar" and b"baz"

Or you can use serde(with serde feature, enabled by default)

```rust use serde_querystring::de;

let parsed: MyStruct = de::from_str("foo=bar&foo=baz", de::ParseMode::Duplicate).unwrap(); ```

There is also serde-querystring-actix crate to support actix-web. It provides QueryString extractor which works just like the actix-web's own web::Query but uses serde-querystring to deserialize.

Parsers

UrlEncodedQS or ParseMode::UrlEncoded

Simply parses key=value pairs, accepting only one value per key. In case a key is repeated, we only collect the last value.

DuplicateQS or ParseMode::Duplicate

Just like UrlEncoded mode, except that if a key is repeated, we collect ALL the values for that key which can be collected later as a vector.

DelimiterQS or ParseMode::Delimiter

Uses a delimiter byte to parse multiple values from a slice of value, ex: "key=value1|value2|value3"

BracketsQS or ParseMode::Brackets

Works like the PHP querystring parser, using brackets and subkeys to assign values, ex: "key[a]=value&key[b]=value"

Credit

We use some lines of code from form_urlencoded to parse percent encoded chars.
