Implementations

impl DataResultTree

pub fn new( data_results: SlotMap<DataResultHandle, DataResultNode>, root_handle: Option<DataResultHandle> ) -> Self

pub fn root_handle(&self) -> Option<DataResultHandle>

pub fn root_node(&self) -> Option<&DataResultNode>

pub fn visit<'a>(&'a self, visitor: &mut impl FnMut(&'a DataResultNode) -> bool)

Depth-first traversal of the tree, calling visitor on each result.

Stops traversing a branch if visitor returns false.

pub fn lookup_result(&self, handle: DataResultHandle) -> Option<&DataResult>

Look up a DataResult in the tree based on its handle.

pub fn lookup_node(&self, handle: DataResultHandle) -> Option<&DataResultNode>

Look up a DataResultNode in the tree based on its handle.

pub fn lookup_node_mut( &mut self, handle: DataResultHandle ) -> Option<&mut DataResultNode>

Look up a DataResultNode in the tree based on its handle.

pub fn lookup_node_by_path(&self, path: &EntityPath) -> Option<&DataResultNode>

Look up a DataResultNode in the tree based on an EntityPath.

pub fn lookup_result_by_path(&self, path: &EntityPath) -> Option<&DataResult>

Look up a DataResult in the tree based on an EntityPath.

pub fn is_empty(&self) -> bool

fn visit_recursive<'a>( &'a self, handle: DataResultHandle, visitor: &mut impl FnMut(&'a DataResultNode) -> bool )
