Struct SecurityValidator 

pub struct SecurityValidator { /* private fields */ }

Security validator with configuration-based limits

Implementations

impl SecurityValidator

pub fn new(config: SecurityConfig) -> Self

Create new validator with given security configuration

pub fn validate_input_size(&self, size: usize) -> Result<()>

Validate input size against security limits

pub fn validate_json_depth(&self, depth: usize) -> Result<()>

Validate JSON depth to prevent stack overflow

pub fn validate_json_depth_bytes(&self, input: &[u8]) -> Result<()>

Validate JSON nesting depth by scanning raw bytes ahead of parsing.

Tracks in-string state (a " toggles it, a \ escapes the following byte) so that {/}/[/] bytes inside string literals are never mistaken for structural delimiters — matching the JSON grammar’s own definition of nesting. Intended as a cheap pre-parse guard shared by every JSON entry point, so a parser backend without its own recursion limit (e.g. sonic-rs) cannot be driven into unbounded recursion by a payload whose reported depth was deflated via crafted string content.

pub fn validate_array_length(&self, length: usize) -> Result<()>

Validate array length

pub fn validate_object_keys(&self, key_count: usize) -> Result<()>

Validate object key count

pub fn validate_string_length(&self, length: usize) -> Result<()>

Validate string length

pub fn validate_session_id(&self, session_id: &str) -> Result<()>

Validate session ID format and length

pub fn validate_websocket_frame_size(&self, size: usize) -> Result<()>

Validate WebSocket frame size

pub fn validate_buffer_size(&self, size: usize) -> Result<()>

Validate buffer size for pooling
