}Expand description
A boundary occurrence of a generic instantiation needing its own
specialised codec — Result<A, B>, Option<A>, List<A>, Map<K, V>,
or a generic user record/sum applied to concrete arguments
(Paginated[User], ApiResult[User]).
Moved from bynk-emit/src/emitter/serialisation.rs’s GenericInst as
part of the #855 IR extraction. Variant names are kept exactly as they
were (ResultInst, not the plan’s bare Result, …): bynk-emit’s
emit_generic_helpers_qualified pattern-matches these variants directly.
Phase 2 step 9 (“Generic helpers”) revisited the plan’s bare
Result/Option/List/Map/Record/Sum spelling and kept the
*Inst suffix — see the “Moved verbatim” comment block above this
module’s walk functions for the reasoning (a pure rename of six match
arms with no behavioural or architectural payoff).
Variants§
ResultInst
OptionInst
ListInst
v0.20b: a List[T] boundary instantiation — element-wise wire format.
MapInst
v0.20b: a Map[K, V] boundary instantiation — entries-array wire
format ([[k, v], …]), insertion-ordered.
RecordInst
v0.174 (#592): a generic user-record instantiation Name[args…] — a
monomorphised per-instantiation record codec (serialise_Paginated_User)
specialised to the concrete arguments (ADR 0183 Decision C’s follow-on).
SumInst
#593: a generic user-sum instantiation Name[args…] — a monomorphised
per-instantiation discriminated-union codec (serialise_ApiResult_User),
the sum analogue of WireInst::RecordInst.

§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);
