Struct former_runtime::VectorFormer

pub struct VectorFormer<E, Vector, Former, ContainerEnd> where
    Vector: VectorLike<E> + Debug + PartialEq + Default,
    ContainerEnd: Fn(&mut Former, Option<Vector>),  { /* fields omitted */ }

Class for forming vector-like fields.

Implementations

impl<E, Vector, Former, ContainerEnd> VectorFormer<E, Vector, Former, ContainerEnd> where
    Vector: VectorLike<E> + Debug + PartialEq + Default,
    ContainerEnd: Fn(&mut Former, Option<Vector>), 

pub fn new(
    former: Former,
    container: Option<Vector>,
    on_end: ContainerEnd
) -> Self

Make a new VectorFormer. It should be called by a former generated for your structure.

pub fn replace(self, vector: Vector) -> Self

Set the whole container instead of setting each element individually.

pub fn end(self) -> Former

Return former of your struct moving container there. Should be called after configuring the container.

pub fn push<E2>(self, e: E2) -> Self where
    E2: Into<E>, 

Appends an element to the back of a container. Make a new container if it was not made so far.
