Enum AddEdges

pub enum AddEdges {
    Start,
    End,
    Both,
    Neither,
}

Controls the behavior of Chain::add_all.

This enum determines whether the start or end of the provided items can be used as start or end data for the chain (see individual variants’ descriptions).

Variants

Start

Allows the start (first Chain::depth items) of the provided iterator to be returned by a call to Chain::get_start (or increases the chance of this happening).

Specifically, this increases the chance that a sequence of Nones could be followed by those starting items in the provided iterator.

End

Increases the chance that the last Chain::depth items of the provided iterator could be followed by None.

Both

Performs the behavior of both Self::Start and Self::End.

Neither

Performs neither the behavior of Self::Start nor Self::End.

Trait Implementations

impl Clone for AddEdges

fn clone(&self) -> AddEdges

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for AddEdges

fn eq(&self, other: &AddEdges) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
