}Expand description
One rung of a ModelLadderDef. Full parity with the .harn
ModelLadderStep alias — {model, provider?, label?, when?, options?, family?, capabilities?} — which is also the shape accepted by the
models: option and the model_ladder(...) std constructor. Provider is
optional: when omitted it is inferred from the model id (or the call’s base
provider) at lowering time.
options carries per-step sampling/timeout overrides (same whitelist as
inline models: steps); catalog ladders honor them identically instead of
silently dropping them. when, family, and capabilities are
informational to Harn’s own ladder lowering (they do not affect transport
failover) but are carried through so catalog and inline ladders declare the
same shape and downstream selectors (e.g. harn-cloud free-tier routing) can
read them. All added fields are optional and serde-absent when unset.
Fields§
§model: String§provider: Option<String>§label: Option<String>§when: Option<String>Conditional-routing predicate hint (e.g. "transport_failure"). Mirror
of the .harn alias when? field. Informational to lowering today.
Absent from serialized output when unset.
options: Option<BTreeMap<String, Value>>Per-step sampling/timeout overrides (temperature, max_tokens, top_p,
seed, timeout_ms, fast, …), same whitelist as inline models: steps.
Absent from serialized output when unset.
family: Option<String>Normalized model-family token (e.g. "haiku", "sonnet") carried for
downstream selectors such as harn-cloud’s free-tier routing. Purely
informational to Harn’s own ladder lowering — it does not affect
transport failover. Absent from serialized output when unset.
capabilities: Vec<String>Capability tags this rung claims (e.g. ["vision", "tools"]). Carried
for downstream capability-aware routing; informational to Harn’s own
ladder lowering. Absent from serialized output when empty.

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().

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};

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().

painted.bold();Source§fn rapid_blink(&self) -> 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);
