Struct Params 

pub struct Params { /* private fields */ }

A wrapper around a JSON params object supporting require/permit.

Implementations

impl Params

pub fn new(value: Value) -> Self

Wrap a params value (typically a JSON object).

pub fn require(&self, key: &str) -> Result<Params>

Return the nested params under key, erroring if it is absent (Rails params.require(:key)).

pub fn permit(&self, allowed: &[&str]) -> Params

Keep only the listed top-level keys, dropping everything else (Rails params.permit(:a, :b)). Non-object params become an empty object.

pub fn get(&self, key: &str) -> Option<&Value>

Borrow a raw value by key.

pub fn deserialize<T: DeserializeOwned>(&self) -> Result<T>

Deserialize the (typically permitted) params into a typed value.

pub fn into_value(self) -> Value

Consume into the underlying JSON value.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Params

fn fmt(&self, f: &mut Formatter<'_>) -> Result
