[−][src]Struct sfkv::Store
Simple Flash Key Value Store
Implementations
impl<B: StoreBackend> Store<B>[src]
pub fn new(backend: B) -> Self[src]
wrap a StoreBackend into a store
pub fn read(&self, key: &str) -> Result<Option<&[u8]>, ReadError>[src]
read from key
pub fn read_str(&self, key: &str) -> Result<Option<&str>, ReadError>[src]
read from key, decode UTF-8
pub fn read_value<'a, T: Deserialize<'a>>(
&'a self,
key: &str
) -> Result<Option<T>, Error<B::Error>>[src]
&'a self,
key: &str
) -> Result<Option<T>, Error<B::Error>>
read from key, decode with postcard
pub fn get_bytes_used(&self) -> Result<usize, ReadError>[src]
how many bytes are currently used
equally, offset of free space
pub fn write<V: AsRef<[u8]>>(
&mut self,
key: &str,
value: V
) -> Result<(), Error<B::Error>>[src]
&mut self,
key: &str,
value: V
) -> Result<(), Error<B::Error>>
store a buffer value at key
pub fn write_value<T, V>(
&mut self,
key: &str,
value: &T,
value_buf: V
) -> Result<(), Error<B::Error>> where
T: Serialize,
V: AsMut<[u8]>, [src]
&mut self,
key: &str,
value: &T,
value_buf: V
) -> Result<(), Error<B::Error>> where
T: Serialize,
V: AsMut<[u8]>,
encode with postcard, write at key
pub fn remove(&mut self, key: &str) -> Result<(), Error<B::Error>>[src]
store a 0-byte tombstone value at key
pub fn erase(&mut self) -> Result<(), WriteError<B::Error>>[src]
invokes erase on the backend (this is no compaction!)
