Struct appendix::Index

pub struct Index<K, V> { /* private fields */ }

On-disk index structure mapping keys to values

Implementations

impl<K, V> Index<K, V>where
    K: 'static + Hash + Copy + PartialEq,
    V: 'static + Hash + Copy,

pub fn new<P: AsRef<Path>>(path: &P) -> Result<Self>

Create or load an index at path

pub fn pages(&self) -> usize

Returns how many pages have been allocated so far

pub fn insert(&self, key: K, val: V) -> Result<AlreadyThere>

Inserts a key-value pair into the index, if the key is already present, this is a no-op

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

Looks up a value with key in the index

pub fn flush(&mut self) -> Result<()>

Syncronizes and flushes data to disk

pub fn on_disk_size(&self) -> usize

Get the approximate size on disk for the index
