Enum TreeLocation 

pub enum TreeLocation<Q> {
    Root,
    At(Q),
    Leftmost,
    Rightmost,
    LowerBound(Bound<Q>),
    UpperBound(Bound<Q>),
}

It is used to specify the location of the node in the tree where the cursor should be initially positioned.

Variants

Root

Root of the tree

At(Q)

Position at a specific key

Leftmost

The cursor will be positioned at the leftmost (minimum) node in the tree.

Rightmost

Rightmost (maximum) node in the tree.

LowerBound(Bound<Q>)

The cursor will be positioned at the first node whose key is greater than (or equal) to the given key depending on the bound type.

UpperBound(Bound<Q>)

The cursor will be positioned at the first node whose key is less than (or equal) to the given key depending on the bound type.
