Struct RevertOutcome 

pub struct RevertOutcome {
    pub covered: usize,
    pub reverted: usize,
    pub kept: Vec<KeptSlot>,
    pub wrote: bool,
}

What a revert did, and what it deliberately did not do.

Fields

covered: usize

Changes the run covered.

reverted: usize

Slots whose effect was inverted.

kept: Vec<KeptSlot>

Slots left alone because somebody edited them after the run. Empty is the ordinary case; non-empty means this revert was partial and the caller must say so.

wrote: bool

True when the document changed. A run whose effect had already been undone reverts nothing and is not an error.

Implementations

impl RevertOutcome

pub fn is_complete(&self) -> bool

True when every slot the run wrote was inverted — i.e. the caller may report that the work was undone completely.

pub fn blocked_by(&self) -> Vec<HistoryAuthor>

Distinct people whose later edits held part of the run back, in first-seen order.

Trait Implementations

impl Clone for RevertOutcome

fn clone(&self) -> RevertOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RevertOutcome

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

Formats the value using the given formatter.

impl Default for RevertOutcome

fn default() -> RevertOutcome

Returns the “default value” for a type.

impl PartialEq for RevertOutcome

fn eq(&self, other: &RevertOutcome) -> 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.
