pub struct Step {
pub delivery: Delivery,
pub step_number: u32,
pub payload: Vec<u8>,
pub signal: Option<Vec<u8>>,
}Expand description
A single step within a workflow run, handed to StepRunner::run_step:
the Delivery it runs under, which it dereferences to, plus the
step number, the step’s payload and the signal that reached it.
Mirrors taquba::JobRecord: the payload is opaque application bytes
and headers carries user metadata you set at submission (reserved
workflow.* keys are filtered out before the runner sees them).
Constructed by the runtime. A test constructs one with
Step::detached and assigns the fields it needs.
Fields§
§delivery: DeliveryThe delivery this step runs under.
step_number: u32Zero-based step number. Step 0 is always the first step of a run, with
the original submission input as its payload.
payload: Vec<u8>Application-defined bytes. For step 0 this is the submission input;
for later steps it is the bytes returned by the previous step’s
StepOutcome::Continue.
signal: Option<Vec<u8>>The signal payload, when this step was reached through a
Trigger::OnSignal wait that a signal resolved: the previous
step continued with OnSignal, and a
crate::WorkflowRuntime::signal call for the correlation key
arrived before the timeout. None when the timeout elapsed first
and on every step not preceded by an OnSignal wait.
Implementations§
Source§impl Step
impl Step
Sourcepub fn detached(payload: impl Into<Vec<u8>>) -> Self
pub fn detached(payload: impl Into<Vec<u8>>) -> Self
Step 0 of a Delivery::detached delivery with payload and no
signal, for tests.
use taquba_workflow::Step;
let mut step = Step::detached(b"input");
step.step_number = 2;
step.attempts = 3;
assert_eq!(step.payload, b"input");
assert!(step.is_last_attempt());Methods from Deref<Target = Delivery>§
Sourcepub fn is_last_attempt(&self) -> bool
pub fn is_last_attempt(&self) -> bool
Whether this attempt is the last: a transient StepError
returned from it dead-letters the step and ends the run.

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.

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);
