Struct DocumentEditor 

pub struct DocumentEditor;

Stateless entry point for typed editor operations.

Implementations

impl DocumentEditor

pub fn plan(input: &[u8], request: &EditRequest) -> Result<EditPlan, EditError>

Validate a request and return its semantic dry-run plan.

Validation applies every operation to a private mutation clone, so a later invalid operation is reported before the caller receives any output bytes or touches a destination path.

pub fn apply(input: &[u8], request: &EditRequest) -> Result<Vec<u8>, EditError>

Validate and apply a request, returning the edited DjVu bytes.

pub fn apply_to_path( input: &Path, output: &Path, request: &EditRequest, ) -> Result<(), EditError>

Validate, apply, and atomically replace output with the edited bytes.

The complete request is validated before a sibling temporary file is created. The temporary file is flushed and synced before rename, so a failed request leaves an existing output untouched.
