pub struct StreamActivity(/* private fields */);Expand description
Shared monotonic counter bumped every time a streaming parser receives a byte chunk from the wire — including chunks that dispatch no item (SSE keepalive comments, a multipart part header block arriving on its own). Streaming clients snapshot it around an idle wait so a low-data-rate stream kept alive purely by non-dispatching traffic is recognised as active rather than idle (the idle timeout must be idle).
Framing-neutral so the streaming driver can apply one idle rule to every
framing: crate::runtime::multipart::MultipartStream exposes the same
handle as SseStream does.
Wraps Arc<AtomicU64> as a newtype so the atomic choice isn’t part of the
public surface.
Implementations§
Source§impl StreamActivity
impl StreamActivity
Sourcepub fn new() -> StreamActivity
pub fn new() -> StreamActivity
Create a fresh activity counter at generation 0.
Sourcepub fn generation(&self) -> u64
pub fn generation(&self) -> u64
Current activity generation. Compare two snapshots to detect whether any wire chunk arrived in between.

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().

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;

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().

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:
