Struct ParameterValidator 

pub struct ParameterValidator { /* private fields */ }

Parameter validator that uses JSON Schema

Implementations

impl ParameterValidator

pub fn new(schema: Value) -> Result<Self, String>

Create a new parameter validator from a JSON Schema

The schema should describe all parameters with their types and constraints. Each property MUST have a “source” field indicating where the parameter comes from.

Errors

Returns an error if the schema is invalid or malformed.

pub fn requires_headers(&self) -> bool

Whether this validator needs access to request headers.

pub fn requires_cookies(&self) -> bool

Whether this validator needs access to request cookies.

pub fn has_params(&self) -> bool

Whether the validator has any parameter definitions.

pub fn schema(&self) -> &Value

Get the underlying JSON Schema

pub fn validate_and_extract( &self, query_params: &Value, raw_query_params: &HashMap<String, Vec<String>>, path_params: &HashMap<String, String>, headers: &HashMap<String, String>, cookies: &HashMap<String, String>, ) -> Result<Value, ValidationError>

Validate and extract parameters from the request

This builds a JSON object from query/path/header/cookie params and validates it. It performs type coercion (e.g., “123” → 123) based on the schema.

Returns the validated JSON object that can be directly converted to Python kwargs.

Errors

Returns a validation error if parameter validation fails.
