) -> RelationResult

pub fn insert(one: RawRelation) -> Result<usize>

pub fn delete(one: RawRelation) -> Result<usize>

pub fn update_flag(from: &str, to: &str, flag_f: i32) -> Result<usize>

from and to's form are full_key:version

pub fn insert_by_biz(
    from: &str,
    to: &str,
    url: &str,
    protocol: &str
) -> Result<RawRelation>

version will be set to 0
