Implementations

impl<T, S> Validator<T, S>

pub fn is_custom(&self) -> bool

pub fn run<C>(&self, ctx: C) -> Option<S>

where C: Into<ValidationContext<T>>,

Convert into the context and run

pub fn run_if<F>(&self, f: F) -> Option<S>

where F: FnOnce() -> ValidationContext<T>,

Only convert when necessary, and run.

pub fn run_ctx(&self, ctx: ValidationContext<T>) -> Option<S>

Run with the provided context.

Trait Implementations

impl<T: Clone, S: Clone> Clone for Validator<T, S>

fn clone(&self) -> Validator<T, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T, S> Default for Validator<T, S>

fn default() -> Self

Returns the “default value” for a type.

impl<F, T, S> From<F> for Validator<T, S>

where F: Fn(ValidationContext<T>) -> S + 'static,

fn from(v: F) -> Self

Converts to this type from the input type.

impl<T, S> PartialEq for Validator<T, S>

Validators are equal if they are still None. Everything else is a change.

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
