pub struct ProgressBus { /* private fields */ }Expand description
Per-connection progress notifier.
Cheap to clone — every clone shares the same outbound sink and the same “last-progress” map used to enforce monotonicity.
Implementations§
Source§impl ProgressBus
impl ProgressBus
pub fn new(outbound: OutboundFn) -> Self
Sourcepub fn from_mpsc(tx: UnboundedSender<JsonValue>) -> Self
pub fn from_mpsc(tx: UnboundedSender<JsonValue>) -> Self
Convenience constructor that wraps a tokio::sync::mpsc
unbounded sender — the shape used by the stdio MCP server.
Sourcepub fn report(
&self,
token: &JsonValue,
progress: f64,
total: Option<f64>,
message: Option<String>,
) -> bool
pub fn report( &self, token: &JsonValue, progress: f64, total: Option<f64>, message: Option<String>, ) -> bool
Emit a notifications/progress notification for token.
Per spec the progress value MUST monotonically increase across
calls with the same token. We silently drop any update that would
regress so a buggy handler can’t violate the contract on the
wire; the user-visible builtin returns false in that case so
scripts can detect it if they care.

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().

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.

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);
