+//! HTTP Response Compression Configuration
+//!
+//! This module provides configuration options for HTTP response compression.
+//! By default, compression is disabled (aligned with MinIO behavior).
+//! When enabled via `RUSTFS_COMPRESS_ENABLE=on`, compression can be configured
+//! to apply only to specific file extensions, MIME types, and minimum file sizes.
+
+/// Environment variable to enable/disable HTTP response compression
+/// Default: off (disabled)
+/// Values: on, off, true, false, yes, no, 1, 0
+/// Example: RUSTFS_COMPRESS_ENABLE=on
+pub const ENV_COMPRESS_ENABLE: &str = "RUSTFS_COMPRESS_ENABLE";
+
+/// Default compression enable state
+/// Aligned with MinIO behavior - compression is disabled by default
+pub const DEFAULT_COMPRESS_ENABLE: bool = false;
+
+/// Environment variable for file extensions that should be compressed
+/// Comma-separated list of file extensions (with or without leading dot)
+/// Default: "" (empty, meaning use MIME type matching only)
+/// Example: RUSTFS_COMPRESS_EXTENSIONS=.txt,.log,.csv,.json,.xml,.html,.css,.js
+pub const ENV_COMPRESS_EXTENSIONS: &str = "RUSTFS_COMPRESS_EXTENSIONS";
+
+/// Default file extensions for compression
+/// Empty by default - relies on MIME type matching
+pub const DEFAULT_COMPRESS_EXTENSIONS: &str = "";
+
+/// Environment variable for MIME types that should be compressed
+/// Comma-separated list of MIME types, supports wildcard (*) for subtypes
+/// Default: "text/*,application/json,application/xml,application/javascript"
+/// Example: RUSTFS_COMPRESS_MIME_TYPES=text/*,application/json,application/xml
+pub const ENV_COMPRESS_MIME_TYPES: &str = "RUSTFS_COMPRESS_MIME_TYPES";
+
+/// Default MIME types for compression
+/// Includes common text-based content types that benefit from compression
+pub const DEFAULT_COMPRESS_MIME_TYPES: &str = "text/*,application/json,application/xml,application/javascript";
+
+/// Environment variable for minimum file size to apply compression
+/// Files smaller than this size will not be compressed
+/// Default: 1000 (bytes)
+/// Example: RUSTFS_COMPRESS_MIN_SIZE=1000
+pub const ENV_COMPRESS_MIN_SIZE: &str = "RUSTFS_COMPRESS_MIN_SIZE";
+
+/// Default minimum file size for compression (in bytes)
+/// Files smaller than 1000 bytes typically don't benefit from compression
+/// and the compression overhead may outweigh the benefits
+pub const DEFAULT_COMPRESS_MIN_SIZE: u64 = 1000;
