Struct dtypes::redis::List

pub struct List<T> { /* private fields */ }

A list that is stored in Redis.

Example

use dtypes::redis::List;

let client = redis::Client::open("redis://localhost:6379").unwrap();
let mut list = List::new("test_list", client);
list.push_back(&1);
list.push_back(&2);
assert_eq!(list.len(), 2);
assert_eq!(list.pop_front(), Some(1));
list.clear();

Implementations

impl<T> List<T>where T: Serialize + DeserializeOwned,

pub fn new(key: &str, client: Client) -> Self

Creates a new List

There is no with_value method like (Generic::with_value)crate::redis::Generic::with_value because it is not possible to provide a good default behaviour in redis. So you have to think about, how you want to handle already stored values in redis. If you want a small performance boost, look at ListCache.

pub fn iter(&self) -> ListIter<'_, T>

Returns an iterator over the list.

pub fn push_front(&mut self, val: &T)

Add a value to the front of the list

pub fn push_back(&mut self, val: &T)

Add a value to the back of the list

pub fn pop_front(&mut self) -> Option<T>

Removes and returns the first value of the list

pub fn pop_back(&mut self) -> Option<T>

Removes and returns the last value of the list

pub fn len(&self) -> usize

Returns the length of the list

pub fn clear(&self)

Removes all values from the list

pub fn contains(&self, val: &T) -> boolwhere T: PartialEq,

Returns true if the list contains the value

pub fn is_empty(&self) -> bool

Returns true if the list is empty
