Struct ChangeCapabilities 

pub struct ChangeCapabilities {
    pub anchored: Option<AnchoredChangeCapabilities>,
    pub snapshot_diff: bool,
    pub external_invalidation: bool,
}

Supported strategies for discovering remote changes.

Fields

anchored: Option<AnchoredChangeCapabilities>

Anchored change-feed support and its guarantees.

snapshot_diff: bool

Core may compare a persisted baseline with a current full snapshot.

external_invalidation: bool

An external caller may explicitly invalidate a scope or item.

Implementations

impl ChangeCapabilities

pub const fn intersection(self, other: Self) -> Self

Computes change-discovery strategies shared by both sides.

Trait Implementations

impl Clone for ChangeCapabilities

fn clone(&self) -> ChangeCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeCapabilities

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

Formats the value using the given formatter.

impl Default for ChangeCapabilities

fn default() -> ChangeCapabilities

Returns the “default value” for a type.

impl PartialEq for ChangeCapabilities

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