Struct PackImport 

pub struct PackImport { /* private fields */ }

An import in steps, so a caller can lock the library per item, show progress and stop between items: PackImport::prepare, then PackImport::start, then PackImport::step until it returns None. import_pack runs all of it at once.

Implementations

impl PackImport

pub fn prepare( lib: &Library, pack: &Path, extracted: TempDir, opts: &PackImportOptions, ) -> Result<PackImport>

Reads the unpacked pack and works out the new items and ids, without changing the library.

pub fn len(&self) -> usize

Items left to import (before the first step: all of them).

pub fn is_empty(&self) -> bool

pub fn total(&self) -> usize

How many items the import holds in all.

pub fn start(&mut self, lib: &mut Library) -> Result<()>

Adds a folder pack’s folder tree to the library.

pub fn step(&mut self, lib: &mut Library) -> Result<Option<String>>

Imports the next item and returns its new id, or None when all are in.
