Struct TreeRevision 

pub struct TreeRevision(/* private fields */);

A monotonically increasing revision of model, filter, or sorting data.

The projection cache is rebuilt whenever any participating revision changes. A TreeModel implementation must return a new value after changing its contents.

Implementations

impl TreeRevision

pub const INITIAL: Self

The initial revision of an immutable value.

pub const fn new(value: u64) -> Self

Creates a revision from an external counter.

pub const fn get(self) -> u64

Returns the numeric revision value.

pub const fn next(self) -> Self

Returns the next revision.

pub const fn advance(&mut self)

Advances the counter to the next revision.

impl PartialEq for TreeRevision

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for TreeRevision

fn partial_cmp(&self, other: &TreeRevision) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.
