Struct serde_qs::Config

pub struct Config { /* private fields */ }

To override the default serialization parameters, first construct a new Config.

The strict parameter controls whether the deserializer will tolerate encoded brackets as part of the key. For example, serializing the field a = vec![12] might give a[0]=12. In strict mode, the only string accepted will be this string, whereas in non-strict mode, this can also be deserialized from a%5B0%5D=12. Strict mode is more accurate for cases where it a field may contain square brackets. In non-strict mode, the deserializer will generally tolerate unexpected characters.

A max_depth of 0 implies no nesting: the result will be a flat map. This is mostly useful when the maximum nested depth is known beforehand, to prevent denial of service attacks by providing incredibly deeply nested inputs.

The default value for max_depth is 5, and the default mode is strict=true.

use serde_qs::Config;
use std::collections::HashMap;

let config = Config::new(0, true);
let map: HashMap<String, String> = config.deserialize_str("a[b][c]=1")
                                         .unwrap();
assert_eq!(map.get("a[b][c]").unwrap(), "1");

let config = Config::new(10, true);
let map: HashMap<String, HashMap<String, HashMap<String, String>>> =
            config.deserialize_str("a[b][c]=1").unwrap();
assert_eq!(map.get("a").unwrap().get("b").unwrap().get("c").unwrap(), "1");

Implementations

impl Config

pub fn new(max_depth: usize, strict: bool) -> Self

Create a new Config with the specified max_depth and strict mode.

impl Config

pub fn deserialize_bytes<'de, T: Deserialize<'de>>( &self, input: &'de [u8] ) -> Result<T, Error>

Deserializes a querystring from a &[u8] using this Config.

pub fn deserialize_str<'de, T: Deserialize<'de>>( &self, input: &'de str ) -> Result<T, Error>

Deserializes a querystring from a &str using this Config.
