Struct cushy::value::Validations

pub struct Validations { /* private fields */ }

A grouping of validations that can be checked simultaneously.

Implementations

impl Validations

pub fn validate<T, E, Valid>( &self, dynamic: &Dynamic<T>, check: Valid ) -> Dynamic<Validation>

where T: Send + 'static, Valid: for<'a> FnMut(&'a T) -> Result<(), E> + Send + 'static, E: Display,

Validates dynamic’s contents using check, returning a dynamic containing the validation status.

The validation is linked with self such that checking self’s validation status will include this validation.

pub fn validate_result<T, E>( &self, result: impl IntoDynamic<Result<T, E>> ) -> Dynamic<Validation>

where T: Send + 'static, E: Display + Send + 'static,

Returns a dynamic validation status that is created by transforming the Err variant of result using Display.

The validation is linked with self such that checking self’s validation status will include this validation.

pub fn when(&self, condition: impl IntoDynamic<bool>) -> WhenValidation<'_>

Returns a builder that can be used to create validations that only run when condition is true.

pub fn when_not(&self, condition: impl IntoDynamic<bool>) -> WhenValidation<'_>

Returns a builder that can be used to create validations that only run when condition is false.

pub fn is_valid(&self) -> bool

Returns true if this set of validations are all valid.

pub fn when_valid<T, R, F>( self, handler: F ) -> impl FnMut(T) -> R + Send + 'static

where F: FnMut(T) -> R + Send + 'static, R: Default,

Returns a function that invokes handler only when all tracked validations are valid.

The returned function can be use in a Callback.

When the contents are invalid, R::default() is returned.

pub fn reset(&self)

Resets the validation status for all related validations.

Trait Implementations

impl Clone for Validations

fn clone(&self) -> Validations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Validations

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

Formats the value using the given formatter.

impl Default for Validations

fn default() -> Validations

Returns the “default value” for a type.
