pub struct Key(/* private fields */);
Expand description
A type identifying a spot in the hierarchy of Tree
items.
Implementations§
source§impl Key
impl Key
sourcepub fn add_child(self, child_id: u16) -> Key
pub fn add_child(self, child_id: u16) -> Key
Return the key to the child identified by child_id
located in a new nesting level below self
.
sourcepub fn level(&self) -> Level
pub fn level(&self) -> Level
The level of hierarchy a node is placed in, i.e. the amount of path components
Return true if the item identified by other
shares the parent at parent_level
.
