Struct AccountTree 

pub struct AccountTree<'arena> { /* private fields */ }

Represents the tree structure of the accounts, stored in the [AccountStore].

Implementations

impl<'arena> AccountTree<'arena>

pub fn new(arena: &'arena Bump) -> Self

Creates a new instance.

This constructs only a plain empty tree, and the actual work is done in Self::construct() because we want to retain the prefixes lifetime aligned with [AccountStore].

pub fn construct(&mut self, accounts: &AccountStore<'arena>)

Constructs the tree state from the given [AccountStore].

pub fn resolve_ancestor(&self, label: &str) -> Option<AccountAncestor<'arena>>

Resolves the [AccountAncestor] corresponding to the given label. Returns None if not found. Note that this would also return None if the given label is Account. See super::ReportContext::account_aggregate(), that is more convenient.

pub fn parent<T: Into<AccountAggregate<'arena>>>( &self, account: T, ) -> Option<AccountTreeKey<'arena>>

Returns the parent of the given node. None if the given account is not found in the tree.

pub fn children<T: Into<AccountTreeKey<'arena>>>( &self, key: T, ) -> Option<&[AccountAggregate<'arena>]>

Returns the children of the given node. None if the given key is not found, and empty slice for the leaf account.
