Function yrs::ymap

#[no_mangle]
pub unsafe extern "C" fn ymap(
    txn: *mut Transaction, 
    name: *const c_char
) -> *mut Map

Gets or creates a new shared YMap data type instance as a root-level type of a given document. This structure can later be accessed using its name, which must be a null-terminated UTF-8 compatible string.

Use ymap_destroy in order to release pointer returned that way - keep in mind that this will not remove YMap instance from the document itself (once created it’ll last for the entire lifecycle of a document).
