Struct NoDbExt

pub struct NoDbExt<'a> { /* private fields */ }

A struct for extending NoDb lists and adding more items to them.

Implementations

impl<'a> NoDbExt<'a>

pub fn ladd<V: Serialize>(&mut self, value: V) -> Option<NoDbExt<'_>>

Add a single item to an existing list.

As mentioned before, the lists are heterogeneous, meaning a single list can contain items of different types. That means that the item can be of any type that is serializable. That includes all primitive types, vectors, tuples and every struct that has the #[derive(Serialize, Deserialize) attribute. The method returns another NoDbExt object that enables to continue adding items to the list.

pub fn lextend<'b, V, I>(&mut self, seq: I) -> Option<NoDbExt<'_>>

where V: 'b + Serialize, I: IntoIterator<Item = &'b V>,

Add multiple items to an existing list.

As mentioned before, the lists are heterogeneous, meaning a single list can contain items of different types. That means that the item can be of any type that is serializable. That includes all primitive types, vectors, tuples and every struct that has the #[derive(Serialize, Deserialize) attribute. This method adds multiple items to the list, but since they’re in a vector that means all of them are of the same type. Of course it doesn’t mean that the list cannot contain items of other types as well, as you can see in the example below. The method returns another NoDbExt object that enables to continue adding items to the list.
