Struct cola::Anchor

pub struct Anchor { /* private fields */ }

A stable reference to a position in a Replica.

After its creation, an Anchor can be given to a Replica to retrieve the current offset of the position it refers to, taking into account all the edits that have been applied to the Replica in the meantime.

This property makes Anchors useful to implement things like cursors and selections in collaborative editing environments. For more information, see the documentation of Replica::create_anchor() and Replica::resolve_anchor().

Trait Implementations

impl Clone for Anchor

fn clone(&self) -> Anchor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Anchor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Anchor

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Anchor

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Anchor

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Anchor

impl Eq for Anchor

impl StructuralPartialEq for Anchor
