Struct ZipHandler 

Source 
pub struct ZipHandler;

Implementations§

Source§

impl ZipHandler

Source

pub fn new() -> Result<Self, ServiceError>

Source

pub async fn validate_package( &self, _zip_path: &Path, ) -> Result<(), ServiceError>

Validate ZIP package structure

Source

pub fn extract_to_dir( &self, zip_path: &Path, dest_dir: &Path, ) -> Result<(), ServiceError>

Safely extract a ZIP file to a destination directory

This function protects against ZIP slip attacks by:

  • Normalizing the output path for each entry
  • Verifying that the normalized path stays within the extraction directory
  • Rejecting entries that would create files outside the extraction root
  • Rejecting symlink entries
§Arguments
  • zip_path - Path to the ZIP file to extract
  • dest_dir - Destination directory for extraction (must exist)
§Errors

Returns ServiceError::Io for I/O errors Returns ServiceError::Validation if path traversal is detected
