Struct TreeState 

pub struct TreeState {
    pub size: u64,
    pub root: Hash,
}

What .state/treeState holds: the size and the root the tiles are complete to. Two lines, the decimal size and the lower-case hex root.

Fields

size: u64

Entries the tiles are complete to.

root: Hash

The root at that size.

Implementations

impl TreeState

pub fn read(store: &impl TileStore) -> Result<Option<Self>>

The state the store holds, or nothing for a store without one.

pub fn parse(text: &str) -> Result<Self>

The state in its two-line text.

pub fn to_text(&self) -> String

The two-line text.

pub fn write(&self, store: &impl TileStore) -> Result<()>

Writes the state, whole or not at all.

Trait Implementations

impl Clone for TreeState

fn clone(&self) -> TreeState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreeState

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

Formats the value using the given formatter.

impl PartialEq for TreeState

fn eq(&self, other: &TreeState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
