Function yrs::ybranch_get

#[no_mangle]
pub unsafe extern "C" fn ybranch_get(
    branch_id: *const YBranchId,
    txn: *mut Transaction
) -> *mut Branch

Given a logical identifier, returns a physical pointer to a shared collection. Returns null if collection was not found - either because it was not defined or not synchronized yet. Returned pointer may still point to deleted collection. In such case a subsequent ybranch_alive function call is required.
