Struct ValidationLimits 

pub struct ValidationLimits {
    pub cache_size: usize,
    pub max_relays_per_group: usize,
    pub max_messages_per_group: usize,
    pub max_group_name_length: usize,
    pub max_group_description_length: usize,
    pub max_admins_per_group: usize,
    pub max_relays_per_welcome: usize,
    pub max_admins_per_welcome: usize,
    pub max_relay_url_length: usize,
}

Configurable validation limits for memory storage.

This struct allows customization of the various limits used to prevent memory exhaustion attacks. All limits have sensible defaults that can be overridden using the builder pattern.

Example

use mdk_memory_storage::ValidationLimits;

let limits = ValidationLimits::default()
    .with_cache_size(2000)
    .with_max_messages_per_group(5000)
    .with_max_relays_per_group(50);

Fields

cache_size: usize

Maximum number of items in each LRU cache

max_relays_per_group: usize

Maximum number of relays allowed per group

max_messages_per_group: usize

Maximum number of messages stored per group

max_group_name_length: usize

Maximum length of a group name in bytes

max_group_description_length: usize

Maximum length of a group description in bytes

max_admins_per_group: usize

Maximum number of admin pubkeys per group

max_relays_per_welcome: usize

Maximum number of relays in a welcome message

max_admins_per_welcome: usize

Maximum number of admin pubkeys in a welcome message

max_relay_url_length: usize

Maximum length of a relay URL in bytes
