Struct Limits 

pub struct Limits {
    pub max_string_length: u32,
    pub max_depth: usize,
    pub max_elements: usize,
}

Limits applied during deserialization to prevent excessive resource usage.

This is modeled after the PHP extension’s dd_mpack_limits structure:

• max_string_length: Strings longer than this are truncated
• max_depth: Maximum nesting depth; deeper structures become null
• max_elements: Maximum total elements; excess elements are skipped

Example

use libddwaf::serde::Limits;

let limits = Limits::default();
assert_eq!(limits.max_string_length, 4096);
assert_eq!(limits.max_depth, 21);
assert_eq!(limits.max_elements, 2048);

// Create custom limits
let custom = Limits {
    max_string_length: 1024,
    max_depth: 10,
    max_elements: 100,
};

Fields

max_string_length: u32

max_depth: usize

max_elements: usize
