Struct CompressionBombConfig 

pub struct CompressionBombConfig {
    pub max_ratio: f64,
    pub max_decompressed_size: usize,
    pub max_compressed_size: usize,
    pub max_compression_depth: usize,
    pub check_interval_bytes: usize,
}

Configuration for compression bomb protection.

max_ratio is a security parameter: it limits how much the decompressed output may exceed the compressed input. Legitimate high-compression workloads (e.g., repetitive JSON with brotli) can exceed 200x; increase this field if you see false positives. Default is 300.0 which is permissive enough for real brotli/gzip workloads while still catching true bombs.

Fields

max_ratio: f64

Maximum allowed compression ratio (decompressed_size / compressed_size). This is a security parameter — see struct-level note.

max_decompressed_size: usize

Maximum allowed decompressed size in bytes.

max_compressed_size: usize

Maximum compressed input size in bytes. Reject inputs larger than this before decoding. Defaults to 100 MiB. This is separate from max_decompressed_size — a legitimately small compressed payload is expected to be far less than the decompressed limit.

max_compression_depth: usize

Maximum nested compression levels.

check_interval_bytes: usize

Check interval - how often to check during decompression.
