Struct ValidationService 

pub struct ValidationService { /* private fields */ }

Schema validation service

Validates JSON data against schema definitions following a subset of JSON Schema specification. Designed for high-performance validation in streaming scenarios.

Design Philosophy

• Zero allocation validation where possible
• Early exit on validation failures for performance
• Detailed error messages with full path context
• Composable validators for complex schemas

Examples

let validator = ValidationService::new();
let schema = Schema::integer(Some(0), Some(100));
let data = JsonData::Integer(50);

assert!(validator.validate(&data, &schema, "/value").is_ok());

Implementations

impl ValidationService

pub fn new() -> Self

Create a new validation service with default configuration

pub fn with_max_depth(max_depth: usize) -> Self

Create validation service with custom maximum depth

Arguments

• max_depth - Maximum nested validation depth

pub fn validate( &self, data: &JsonData, schema: &Schema, path: &str, ) -> SchemaValidationResult<()>

Validate JSON data against a schema

Performs comprehensive validation of JSON data against the provided schema, including type checking, constraint validation, and nested structure validation.

Arguments

• data - JSON data to validate
• schema - Schema to validate against
• path - Current JSON path for error reporting

Returns

Ok(()) if validation succeeds, error with details if validation fails

Errors

Returns SchemaValidationError with context when validation fails

Trait Implementations

impl Default for ValidationService

fn default() -> Self

Returns the “default value” for a type.
