Enum MoveGroupError 

#[non_exhaustive]
pub enum MoveGroupError {
    CannotMoveRoot,
    NotFound(GroupId),
    WouldCreateCycle,
}

Errors that can occur when moving a group to a new parent.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CannotMoveRoot

The root group cannot be moved

NotFound(GroupId)

The destination group was not found in the database.

This error can also occur if the destination group belongs to a different database.

WouldCreateCycle

Moving the group would create a cycle in the group hierarchy, which is not allowed.
