Module config 

Configuration for Automorph behavior. Configuration for Automorph behavior.

This module provides configuration options that can be set globally or per-thread.

Collection Size Limits

By default, Automorph limits collections to DEFAULT_MAX_COLLECTION_SIZE (10 million) elements to prevent memory exhaustion from malicious documents.

You can override this limit globally or for a specific scope:

use automorph::config;

// Set a global limit (affects all threads until changed)
config::set_max_collection_size(1_000_000);

// Or use a scoped limit that automatically restores the previous value
config::with_max_collection_size(100, || {
    // Within this closure, max collection size is 100
    // After the closure returns, the previous limit is restored
});

Constants

DEFAULT_MAX_COLLECTION_SIZE

Functions

set_max_collection_size

with_max_collection_size
