Struct ValidationContext 

pub struct ValidationContext { /* private fields */ }

Context for validation operations.

Provides runtime state during validation, including:

• Field values for cross-field validation
• Metadata storage
• Locale settings for i18n

Example

use skp_validator_core::ValidationContext;

let ctx = ValidationContext::new()
    .with_locale("en")
    .with_meta("request_id", "123");

Implementations
