Struct ResourceLimits 

pub struct ResourceLimits {
    pub max_file_size_bytes: usize,
    pub max_expression_depth: usize,
    pub max_fact_value_bytes: usize,
    pub max_evaluation_time_ms: u64,
}

Resource limits to prevent abuse and enable predictable memory usage

These limits protect against malicious inputs while being generous enough for all legitimate use cases.

Fields

max_file_size_bytes: usize

Maximum file size in bytes Real usage: ~5KB, Limit: 5MB (1000x)

max_expression_depth: usize

Maximum expression nesting depth Real usage: ~3 levels, Limit: 100 (30x+)

max_fact_value_bytes: usize

Maximum size of a single fact value in bytes Real usage: ~100 bytes, Limit: 1KB (10x) Enables server pre-allocation for zero-allocation evaluation

max_evaluation_time_ms: u64

Maximum evaluation time in milliseconds Real usage: ~1-10ms, Limit: 1000ms (100-1000x)
