Struct ParseOptions 

pub struct ParseOptions {
    pub max_key_len: usize,
    pub max_collection_elements: usize,
    pub max_bulk_string_len: usize,
    pub max_depth: usize,
    pub max_total_items: usize,
}

Configuration options for RESP value parsing.

These options allow customizing the DoS protection limits for different deployment scenarios. More restrictive limits provide better protection against resource exhaustion attacks.

Fields

max_key_len: usize

Maximum key length in bytes.

max_collection_elements: usize

Maximum number of elements in a single collection.

max_bulk_string_len: usize

Maximum size of a bulk string in bytes.

max_depth: usize

Maximum nesting depth for recursive structures.

max_total_items: usize

Maximum total items across all collections in a single parse.

This is the critical limit for preventing exponential allocation attacks from nested collections. Without this, an attacker could send nested arrays where total items = max_collection_elements^max_depth.

Implementations
