Trait RequiredFieldExt 

pub trait RequiredFieldExt<T> {
    // Required method
    fn require_field(self, field_name: &str) -> Result<T, ValidationError>;
}

Extension trait for Option types to simplify required field validation

This trait provides convenient methods to convert None values into ValidationError, reducing boilerplate in builder patterns.

Example

use torii_core::error::utilities::RequiredFieldExt;

// Instead of:
// let email = self.email.ok_or(ValidationError::MissingField("Email is required".to_string()))?;

// Use:
let email = self.email.require_field("Email")?;

Required Methods

fn require_field(self, field_name: &str) -> Result<T, ValidationError>

Convert None to a ValidationError::MissingField
