pub struct LiteChangeStream { /* private fields */ }Expand description
Local change event bus for NodeDB-Lite.
Subscribers register callbacks that fire synchronously on each write. No persistence, no durability — purely for app-level reactivity.
Works on all platforms: native (iOS/Android/desktop) and WASM (browser).
Implementations§
Source§impl LiteChangeStream
impl LiteChangeStream
pub fn new() -> Self
Sourcepub fn subscribe<F>(&self, callback: F) -> Subscription
pub fn subscribe<F>(&self, callback: F) -> Subscription
Subscribe to local change events. Returns a handle that unsubscribes on drop.
The callback fires synchronously on each publish() call — keep it fast.
For async processing, use the callback to send into your own channel.
Sourcepub fn publish(&self, event: &LiteChangeEvent)
pub fn publish(&self, event: &LiteChangeEvent)
Publish a change event to all subscribers.
Sourcepub fn publish_write(
&self,
collection: &str,
document_id: &str,
op: LiteChangeOp,
)
pub fn publish_write( &self, collection: &str, document_id: &str, op: LiteChangeOp, )
Publish a user-originated write event.
Sourcepub fn publish_sync(
&self,
collection: &str,
document_id: &str,
op: LiteChangeOp,
)
pub fn publish_sync( &self, collection: &str, document_id: &str, op: LiteChangeOp, )
Publish a CRDT sync merge event (inbound delta from Origin).
Sourcepub fn events_published(&self) -> u64
pub fn events_published(&self) -> u64
Total events published since creation.
Sourcepub fn subscriber_count(&self) -> usize
pub fn subscriber_count(&self) -> usize
Number of active subscribers.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);Source§impl<T> Pointable for T
