Extension trait for ValidationResult

Required Methods

fn map_valid<U, F>(self, f: F) -> Result<U, ValidationErrors>

where F: FnOnce(T) -> U,

Map the success value, preserving validation errors

fn and_also<U>( self, other: Result<U, ValidationErrors>, ) -> Result<(T, U), ValidationErrors>

Combine with another validation result, collecting all errors

fn with_errors( self, other: Result<(), ValidationErrors>, ) -> Result<T, ValidationErrors>

Add errors from another result without changing the success type

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
