+/// Base log entry structure shared by all log types
+/// This structure is used to serialize log entries to JSON
+/// and send them to the log sinks
+/// This structure is also used to deserialize log entries from JSON
+/// This structure is also used to store log entries in the database
+/// This structure is also used to query log entries from the database
+///
+/// The `BaseLogEntry` structure contains the following fields:
+/// - `timestamp` - the timestamp of the log entry
+/// - `request_id` - the request ID of the log entry
+/// - `message` - the message of the log entry
+/// - `tags` - the tags of the log entry
+///
+/// The `BaseLogEntry` structure contains the following methods:
+/// - `new` - create a new `BaseLogEntry` with default values
+/// - `message` - set the message
+/// - `request_id` - set the request ID
+/// - `tags` - set the tags
+/// - `timestamp` - set the timestamp
+///
+/// # Example
+/// ```
+/// use rustfs_obs::BaseLogEntry;
+/// use chrono::{DateTime, Utc};
+/// use std::collections::HashMap;
+///
+/// let timestamp = Utc::now();
+/// let request = Some("req-123".to_string());
+/// let message = Some("This is a log message".to_string());
+/// let tags = Some(HashMap::new());
+///
+/// let entry = BaseLogEntry::new()
+///     .timestamp(timestamp)
+///     .request_id(request)
+///     .message(message)
+///     .tags(tags);
