Struct TaskManager
pub struct TaskManager { /* private fields */ }Expand description
Many reth components require to spawn tasks for long-running jobs. For example discovery
spawns tasks to handle egress and ingress of udp traffic or network that spawns session tasks
that handle the traffic to and from a peer.
To unify how tasks are created, the TaskManager provides access to the configured Tokio
runtime. A TaskManager stores the [tokio::runtime::Handle] it is associated with. In this
way it is possible to configure on which runtime a task is executed.
The main purpose of this type is to be able to monitor if a critical task panicked, for
diagnostic purposes, since tokio task essentially fail silently. Therefore, this type is a
Stream that yields the name of panicked task, See TaskExecutor::spawn_critical. In order to
execute Tasks use the TaskExecutor type TaskManager::executor.
Implementations§
§impl TaskManager
impl TaskManager
pub fn current() -> TaskManager ⓘ
pub fn current() -> TaskManager ⓘ
Returns a a TaskManager over the currently running Runtime.
§Panics
This will panic if called outside the context of a Tokio runtime.
pub fn new(handle: Handle) -> TaskManager ⓘ
pub fn new(handle: Handle) -> TaskManager ⓘ
Create a new instance connected to the given handle’s tokio runtime.
pub fn executor(&self) -> TaskExecutor
pub fn executor(&self) -> TaskExecutor
Returns a new TaskExecutor that can spawn new tasks onto the tokio runtime this type is
connected to.
pub fn graceful_shutdown(self)
pub fn graceful_shutdown(self)
Fires the shutdown signal and awaits until all tasks are shutdown.
pub fn graceful_shutdown_with_timeout(self, timeout: Duration) -> bool
pub fn graceful_shutdown_with_timeout(self, timeout: Duration) -> bool
Fires the shutdown signal and awaits until all tasks are shutdown.
Returns true if all tasks were shutdown before the timeout elapsed.

§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();§fn bright_black(&self) -> Painted<&T>

§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().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§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();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§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();§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.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§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);§impl<T> Pipe for Twhere
