Enum charcoal::TryRemoveChildrenError

pub enum TryRemoveChildrenError {
    WasLeafNode,
    HadBranchChild(u32),
}

The error type returned by methods on trees which remove children branch nodes.

Variants

WasLeafNode

The node a leaf node and thus cannot have children by definition.

HadBranchChild(u32)

One of the node’s children was a branch node, which would require recursion to remove. Contains the index of the offending node; if there were multiple, the smallest index is specified.
