Struct nebari::tree::ActiveState

source · [−]

pub struct ActiveState<Root: Root> {
    pub file_id: Option<u64>,
    pub current_position: u64,
    pub root: Root,
    pub max_order: Option<usize>,
}

Expand description

An active state for a tree file.

Fields

file_id: Option<u64>

The current file id associated with this tree file. Database compaction will cause the file_id to be changed once the operation succeeds.

current_position: u64

The current location within the file for data to be written.

root: Root

The root of the B-Tree.

max_order: Option<usize>

The maximum “order” of the B-Tree. This controls the maximum number of children any node in the tree may contain. Nebari will automatically scale up to this number as the database grows.

Implementations
