//! BookmarkCollection module
|
|
//!
|
|
//! A BookmarkCollection is nothing more than a simple store entry. One can simply call functions
|
|
//! from the libimagentrylink::external::ExternalLinker trait on this to generate external links.
|
|
//!
|
|
//! The BookmarkCollection type offers helper functions to get all links or such things.
