Struct ValidateService 

pub struct ValidateService { /* private fields */ }

Tower Service implementing the Validate EIP.

If the predicate returns true, the exchange continues (returned as Ok). If false, a CamelError::ValidationError is returned.

Implementations

pub fn new( predicate: impl Fn(&Exchange) -> bool + Send + Sync + 'static, expression_source: impl Into<String>, ) -> Self

Create from a closure predicate and an expression source string (for error messages).

pub fn from_predicate( predicate: FilterPredicate, expression_source: impl Into<String>, ) -> Self

Create from a pre-boxed FilterPredicate (used by resolve_steps).
