Struct tarantool_module::space::Space

pub struct Space { /* fields omitted */ }

Implementations

impl Space

pub fn find(name: &str) -> Option<Self>

Find space by name.

This function performs SELECT request to _vspace system space.

• name - space name

Returns:

• None if not found
• Some(space) otherwise

See also: index_by_name

pub fn system_space(id: SystemSpace) -> Self

Access to system space

pub fn index(&self, name: &str) -> Option<Index>

Find index by name.

This function performs SELECT request to _vindex system space.

• name - index name

Returns:

• None if not found
• Some(index) otherwise

See also: find_by_name

pub fn primary_key(&self) -> Index

Returns index with id = 0

pub fn insert<T>(&mut self, value: &T) -> Result<Option<Tuple>, Error> where
    T: AsTuple, 

Execute an INSERT request.

• value - tuple value to insert

Returns a new tuple.

See also: box.space[space_id]:insert(tuple)

pub fn replace<T>(&mut self, value: &T) -> Result<Option<Tuple>, Error> where
    T: AsTuple, 

Execute an REPLACE request.

• value - tuple value to replace with

Returns a new tuple.

See also: box.space[space_id]:replace(tuple)

pub fn put<T>(&mut self, value: &T) -> Result<Option<Tuple>, Error> where
    T: AsTuple, 

Insert a tuple into a space. If a tuple with the same primary key already exists, replaces the existing tuple with a new one. Alias for replace

pub fn truncate(&mut self) -> Result<(), Error>

Truncate space.

pub fn len(&self) -> Result<usize, Error>

pub fn bsize(&self) -> Result<usize, Error>

pub fn get<K>(&self, key: &K) -> Result<Option<Tuple>, Error> where
    K: AsTuple, 

pub fn delete<K>(&mut self, key: &K) -> Result<Option<Tuple>, Error> where
    K: AsTuple, 

pub fn update<K, Op>(
    &mut self,
    key: &K,
    ops: &Vec<Op>
) -> Result<Option<Tuple>, Error> where
    K: AsTuple,
    Op: AsTuple, 

pub fn upsert<T, Op>(
    &mut self,
    value: &T,
    ops: &Vec<Op>
) -> Result<Option<Tuple>, Error> where
    T: AsTuple,
    Op: AsTuple,
