Struct ConcurrentTrieNode 

pub struct ConcurrentTrieNode {
    pub column_id: Option<ColumnId>,
    pub column_type: Option<ColumnType>,
    pub children: DashMap<String, Arc<ConcurrentTrieNode>>,
    pub created_epoch: u64,
}

A node in the concurrent path trie using epoch-based reclamation

Fields

column_id: Option<ColumnId>

Column ID if this path is a leaf (terminal column)

column_type: Option<ColumnType>

Column type for leaf nodes

children: DashMap<String, Arc<ConcurrentTrieNode>>

Children nodes keyed by path segment (lock-free via DashMap)

created_epoch: u64

Epoch when this node was created (for reclamation)

Implementations

impl ConcurrentTrieNode

pub fn new(epoch: u64) -> Self

Create an empty node

pub fn leaf(column_id: ColumnId, column_type: ColumnType, epoch: u64) -> Self

Create a leaf node with column information

pub fn is_leaf(&self) -> bool

Check if this is a leaf node

pub fn count_nodes(&self) -> usize

Count total nodes in subtree

Trait Implementations

impl Debug for ConcurrentTrieNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
