impl CrdtSubscriptions
pub fn new() -> Arc<Self> ⓘ
Sourcepub fn subscribe(&self, client_id: u64, entity: &str, row_id: &str)
pub fn subscribe(&self, client_id: u64, entity: &str, row_id: &str)
Register a client’s interest in a row. Idempotent — re-subscribing the same client to the same row is a no-op (HashSet semantics).
Sourcepub fn unsubscribe(&self, client_id: u64, entity: &str, row_id: &str)
pub fn unsubscribe(&self, client_id: u64, entity: &str, row_id: &str)
Drop one subscription. Cleans up empty maps so the working set stays bounded — long-running connections that subscribe and unsubscribe to many rows over their lifetime don’t accumulate orphan empty entries.
Sourcepub fn unsubscribe_all(&self, client_id: u64)
pub fn unsubscribe_all(&self, client_id: u64)
Drop every subscription for a client (called on WS disconnect or when a broadcast send fails for that client). Atomic over the whole client’s subscription set — broadcast snapshots taken concurrently see the client either fully present or fully gone.
Sourcepub fn subscribers(&self, entity: &str, row_id: &str) -> Vec<u64>
pub fn subscribers(&self, entity: &str, row_id: &str) -> Vec<u64>
Snapshot the subscriber set for a row. Returns an owned Vec
rather than a guard so the broadcast hot path doesn’t hold the
mutex during the per-client send loop.
Sourcepub fn total_subscriptions(&self) -> usize
pub fn total_subscriptions(&self) -> usize
Diagnostic: total number of (client, row) pairs.

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().

Source§fn bg(&self, value: Color) -> 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);
