Struct Validator 

pub struct Validator { /* private fields */ }

A set of fields, their rules, and the values to run them against.

Implementations

impl Validator

pub fn new(input: impl Into<Input>) -> Self

Validate a bag of values — a JSON body, a form, or an Input built by hand.

pub fn from_request(request: &mut Request) -> Self

Validate a request, remembering whether the client wants JSON back so the failure response can be negotiated later, when the request is gone.

pub fn rule(self, field: impl Into<String>, rules: impl IntoRules) -> Self

Add one field’s rules, as a Laravel string or as a built rule set.

pub fn rules(self, specs: &[(&str, &str)]) -> Self

Add every field at once: .rules(&[("email", "required|email")]).

pub fn message(self, key: impl Into<String>, message: impl Into<String>) -> Self

Override one message. The key is "field.rule" or just "rule".

pub fn attribute( self, field: impl Into<String>, label: impl Into<String>, ) -> Self

Rename a field for display: .attribute("dob", "date of birth").

pub fn with_messages(self, messages: Messages) -> Self

Replace the whole message bag, for an application that keeps its own.

pub fn with_json(self, wants_json: bool) -> Self

Force the failure response to be JSON (or not), overriding what the request negotiated.

pub fn input(&self) -> &Input

pub fn errors(&self) -> Errors

Every message the rules produce. Empty when the input is valid.

pub fn passes(&self) -> bool

pub fn fails(&self) -> bool

pub fn validate(&self) -> Result<Validated, Errors>

The validated subset of the input, or every message that failed.
