Struct louis_sys::ThreadUnsafetyToken

pub struct ThreadUnsafetyToken(_);

A token that can only ever exist once in the context of an entire process. This is needed since liblouis is inherently thread-unsafe. Safe abstractions over this crate have to guard all liblouis function calls, allowing them only if this token is held. Note that the token itself does not enable any safe calling of liblouis functions - higher-level bindings need to provide this.
