Struct tuple_storage::Storage

pub struct Storage { /* fields omitted */ }

Methods

impl Storage

pub fn create(file: File, schema: &str) -> Result<Storage>

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

pub fn open(file: File) -> Result<Storage>

pub fn insert(&mut self, tuple: &mut Tuple) -> Result<(), SchemaError>

Insert does not allow duplicate key and inserts the Tuple in the set in a sorted way

pub fn append(&mut self, tuple: &mut Tuple) -> Result<(), SchemaError>

Append allows duplicate key

pub fn update(&mut self, tuple: &mut Tuple) -> Result<usize, SchemaError>

Update all tuples matching the key

returns how many tuples were updated

pub fn remove_all(&mut self, filter: &Filter) -> usize

Remove all tuples matching the key. Working from the end to the front of the Storage.

pub fn remove(&mut self, filter: &Filter) -> usize

Delete all tuples matching the key sorted

pub fn iter(&self) -> StorageIterator

pub fn get(&self, offset: u64) -> Option<Tuple>

pub fn create_filter(&self, filter: &str) -> Result<Filter, SchemaParseError>

pub fn schema_to_string(&self) -> String
