import debug from "debug";
/**
 * Faast.js loggers.
 * @remarks
 * Unless otherwise specified, each log is disabled by default unless the value
 * of the DEBUG environment variable is set to the corresponding value. For
 * example:
 *
 * ```
 *   $ DEBUG=faast:info,faast:provider <cmd>
 *   $ DEBUG=faast:* <cmd>
 * ```
 *
 * Logs can also be enabled or disabled programmatically:
 * ```typescript
 * import { log } from "faastjs"
 * log.info.enabled = true;
 * log.provider.enabled = true;
 * ```
 *
 * Each log outputs specific information:
 *
 * `info` - General informational logging.
 *
 * `minimal` - Outputs only basic information like the function name created in
 * the cloud.
 *
 * `warn` - Warnings. Enabled by default.
 *
 * `gc` - Garbage collection verbose logging.
 *
 * `leaks` - Memory leak detector warnings for the cloud function. Enabled by
 * default.
 *
 * `calls` - Verbose logging of each faast.js enabled function invocation.
 *
 * `webpack` - Verbose logging from webpack and packaging details.
 *
 * `provider` - Verbose logging of each interaction between faast.js runtime and
 * the provider-specific implementation.
 *
 * `awssdk` - Verbose logging of AWS SDK. This can be useful for identifying
 * which API calls are failing, retrying, or encountering rate limits.
