pub struct FixedKeyProcessorContext<'a, 'ctx, 'd, K, VOut> { /* private fields */ }Expand description
The context handed to FixedKeyProcessor::process.
The only forward re-attaches the unchanged key, so a fixed-key processor
cannot repartition by accident. All other accessors delegate verbatim to the
underlying ProcessorContext.
Implementations§
Source§impl<'a, 'ctx, 'd, K, VOut> FixedKeyProcessorContext<'a, 'ctx, 'd, K, VOut>
impl<'a, 'ctx, 'd, K, VOut> FixedKeyProcessorContext<'a, 'ctx, 'd, K, VOut>
Sourcepub fn forward(&mut self, record: FixedKeyRecord<K, VOut>)
pub fn forward(&mut self, record: FixedKeyRecord<K, VOut>)
Forward a record downstream and re-attach the unchanged key. This mirrors
the JVM FixedKeyProcessorContext.forward(FixedKeyRecord).
Sourcepub fn get_state_store<K2: Send + Sync + 'static, V2: Send + 'static>(
&mut self,
name: &str,
) -> Option<&mut dyn KeyValueStore<K2, V2>>
pub fn get_state_store<K2: Send + Sync + 'static, V2: Send + 'static>( &mut self, name: &str, ) -> Option<&mut dyn KeyValueStore<K2, V2>>
Access a connected key/value state store, typed. This method delegates to
ProcessorContext::get_state_store. This context has no window-store or
session-store accessor, because no DSL path connects those to a
process_values node yet.
Sourcepub fn record_context(&self) -> &RecordContext
pub fn record_context(&self) -> &RecordContext
Metadata of the source record currently being processed.

§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().

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};

§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 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 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);
