Enum DisplacedMarker 

pub enum DisplacedMarker {
    Main {
        id: u64,
        position: usize,
    },
    Margin {
        id: u64,
        position: usize,
    },
}

A marker whose position was displaced by a deletion. Stored in LogEntry (for single edits) or Event::BulkEdit (for bulk edits). On undo, the marker is restored to its exact original position.

Variants

Main

Marker from the main marker_list (virtual text, overlays)

Fields

id: u64

position: usize

Margin

Marker from margins.indicator_markers (breakpoints, line indicators)

Fields

id: u64

position: usize

Implementations

impl DisplacedMarker

pub fn encode(&self) -> (u64, usize)

Encode as (u64, usize) for compact storage. Uses high bit to tag source.

pub fn decode(tagged_id: u64, position: usize) -> Self

Decode from (u64, usize) compact representation.

Trait Implementations

impl Clone for DisplacedMarker

fn clone(&self) -> DisplacedMarker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplacedMarker

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DisplacedMarker

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DisplacedMarker

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