Struct SQLiteMapTransaction 

pub struct SQLiteMapTransaction<'a, K, V>
where
    K: Type,
    V: Type,
{ /* private fields */ }

Represents an active SQLite transaction for a SQLiteMap.

Most functions provided by this struct mirror the corresponding functions of the SQLiteMap struct.

The transaction is committed when the SQLiteMapTransaction is dropped.

Implementations

impl<'a, K, V> SQLiteMapTransaction<'a, K, V>

where K: Type, V: Type,

pub fn commit(self)

Drops the SQLiteMapTransaction, thereby committing the SQLite transaction.

pub fn insert<Q, R>(&mut self, key: &Q, value: &R) -> Result<bool, Error>

where K: Borrow<Q>, Q: ?Sized + ToSql, V: Borrow<R>, R: ?Sized + ToSql,

This function is equivalent to SQLiteMap::insert().

pub fn update<Q, R>(&mut self, key: &Q, value: &R) -> Result<(), Error>

where K: Borrow<Q>, Q: ?Sized + ToSql, V: Borrow<R>, R: ?Sized + ToSql,

This function is equivalent to SQLiteMap::update().

pub fn contains_key<Q>(&self, key: &Q) -> Result<bool, Error>

where K: Borrow<Q>, Q: ?Sized + ToSql,

This function is equivalent to SQLiteMap::contains_key().

pub fn contains_key_nocase<Q>(&self, key: &Q) -> Result<bool, Error>

where K: Borrow<Q> + CharType, Q: ?Sized + ToSql,

This function is equivalent to SQLiteMap::contains_key_nocase().

pub fn get<Q>(&self, key: &Q) -> Result<Option<V>, Error>

where K: Borrow<Q>, Q: ?Sized + ToSql,

This function is equivalent to SQLiteMap::get().

pub fn get_nocase<Q>(&self, key: &Q) -> Result<Option<V>, Error>

where K: Borrow<Q> + CharType, Q: ?Sized + ToSql,

where F: FnMut(K, V),

This function is equivalent to SQLiteMap::for_each_entry().

pub fn find_key<P>(&self, predicate: P) -> Result<Option<K>, Error>

where P: Fn(&K) -> bool,
