Struct Rules 

pub struct Rules { /* private fields */ }

An ordered set of rules for one field.

Order is preserved because it is the order the messages come back in, and a developer who wrote required|email expects to be told about the missing field before the malformed one.

Implementations

impl Rules

pub fn new() -> Self

pub fn parse(spec: &str) -> Result<Rules>

Parse Laravel’s pipe/colon syntax: "required|between:1,10|in:a,b,c".

Whitespace around a rule is ignored and empty segments are dropped, so a spec split across lines in a config file still parses.

pub fn rules(&self) -> &[Rule]

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn has(&self, name: &str) -> bool

Whether a rule with this name is in the set. The validator asks this to find nullable, and to decide whether min counts characters or value.

pub fn push(self, rule: Rule) -> Self

Append an already-built rule. The chaining methods below all go through here.

pub fn required(self) -> Self

pub fn nullable(self) -> Self

pub fn string(self) -> Self

pub fn integer(self) -> Self

pub fn numeric(self) -> Self

pub fn boolean(self) -> Self

pub fn email(self) -> Self

pub fn url(self) -> Self

pub fn min(self, bound: impl Into<f64>) -> Self

pub fn max(self, bound: impl Into<f64>) -> Self

pub fn between(self, low: impl Into<f64>, high: impl Into<f64>) -> Self

pub fn size(self, exact: impl Into<f64>) -> Self

pub fn one_of<S: Into<String>>( self, values: impl IntoIterator<Item = S>, ) -> Self

The builder spelling of in:a,b,c; in is a Rust keyword.

pub fn not_in<S: Into<String>>( self, values: impl IntoIterator<Item = S>, ) -> Self

pub fn confirmed(self) -> Self

pub fn same(self, other: impl Into<String>) -> Self

pub fn different(self, other: impl Into<String>) -> Self

pub fn alpha(self) -> Self

pub fn alpha_num(self) -> Self

pub fn alpha_dash(self) -> Self

pub fn starts_with<S: Into<String>>( self, prefixes: impl IntoIterator<Item = S>, ) -> Self

pub fn ends_with<S: Into<String>>( self, suffixes: impl IntoIterator<Item = S>, ) -> Self

pub fn date(self) -> Self

pub fn uuid(self) -> Self

pub fn array(self) -> Self
