Trait for async validation rules.

Use this for rules that require async operations like database or API checks.

Required Methods

fn validate_async<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, value: &'life1 T, ctx: &'life2 ValidationContext, ) -> Pin<Box<dyn Future<Output = Result<(), RuleError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Validate the value asynchronously.

fn rule_name(&self) -> &'static str

Get the rule name/code for error reporting.

Provided Methods

fn default_message(&self) -> String

Get the default error message for this rule.
