Implementations

impl LogFileManager

pub fn new(config: AuditConfig) -> Result<Self, CoreError>

Create a new log file manager.

Errors

Returns an error if the log directory cannot be created.

pub fn write_event(&mut self, event: &mut AuditEvent) -> Result<(), CoreError>

Write an audit event to the log file.

Errors

Returns an error if the event cannot be serialized or written to the log file.

pub fn rotate_log_file(&mut self) -> Result<(), CoreError>

Rotate the current log file to a new file.

Errors

Returns an error if the current file cannot be flushed or a new file cannot be created.

pub fn cleanup_old_files(&self) -> Result<(), CoreError>

Clean up old log files according to the retention policy.

Errors

Returns an error if log files cannot be read or deleted.

pub fn serialize_json(&self, event: &AuditEvent) -> Result<String, CoreError>

Serialize an audit event to JSON format.

Errors

Returns an error if the event cannot be serialized to JSON.

pub fn serialize_text(&self, event: &AuditEvent) -> String

Serialize an audit event to text format.

pub fn flush(&mut self) -> Result<(), CoreError>

Flush pending data to the log file.

Errors

Returns an error if the file cannot be flushed.

pub fn calculate_event_hash( &self, event: &AuditEvent, ) -> Result<String, CoreError>

Calculate a cryptographic hash for an audit event.

Errors

Returns an error if the hash cannot be calculated.

pub fn verify_hash_chain(&self) -> Result<bool, CoreError>

Verify hash chain integrity

Errors

Returns an error if hash chain verification fails.

pub fn archive_old_files(&self) -> Result<(), CoreError>

Archive old log files according to retention policy

Errors

Returns an error if archival operations fail.

pub fn cleanup_expired_files(&self) -> Result<(), CoreError>

Clean up files according to retention policy

Errors

Returns an error if cleanup operations fail.

pub fn compress_archived_file(&self, file_path: &Path) -> Result<(), CoreError>

Compress an archived log file

Errors

Returns an error if compression fails.

pub fn get_available_disk_space(&self, path: &Path) -> Result<u64, CoreError>

Get available disk space for a directory

Errors

Returns an error if disk space cannot be determined.
