sourcepub async fn build<S>(

pub async fn build<S>( key: S, conn: C, timeout: Option<u8> ) -> Result<Lock<C>, Lock<C>>where S: Into<String> + Debug,
Lock builder
Takes anything can become a String as key, an owned connection (it can be a sea_orm::DatabaseConnection
,
a sea_orm::DatabaseTransaction or another
Lock` himself), and an optional timeout in seconds, defaulting to 1 second
sourcepub async fn release(self) -> Result<C, Unlock<C>>
pub async fn release(self) -> Result<C, Unlock<C>>
releases the lock, returning the owned connection on success
on error it will return the Lock
himself alongside with the database error, if any
sourcepub fn into_inner(self) -> C
pub fn into_inner(self) -> C
forgets the lock and returns inner connection WARNING: the lock will continue to live in the database session
