Struct CapabilityCtx
pub struct CapabilityCtx {
pub capabilities: HashMap<String, CapabilityInfo>,

pub given_used: HashSet<String>,
pub given_entries: Vec<(String, Span)>,

}Expand description
Mutable per-function context.
Capability bookkeeping for the checker — the given-clause lifecycle and
capability dispatch, grouped out of Ctx (v0.29.10). Empty (Default)
for pure functions / non-context code.
Fields§
§capabilities: HashMap<String, CapabilityInfo>Capabilities in scope for the current handler, as a name → CapabilityInfo map. Empty for pure functions and non-context code.
declared_capabilities: HashMap<String, CapabilityInfo>All capabilities declared in the surrounding context (for diagnostic
purposes — used to detect <Cap>.op(...) calls where the capability is
declared in the context but not listed in given).
given_remaining: HashSet<String>Names of capabilities the user listed in given, but haven’t yet
observed used. After checking the body, anything left here is
unused — a warning.
given_used: HashSet<String>Names of capabilities actually used in the body so far.
given_entries: Vec<(String, Span)>v0.26 (ADR 0054): the given clause’s entries in declaration order —
(deps key, source span) — so the given quick-fixes can author
list-aware edits at the diagnosis site. Empty where no given clause
applies (fns, mock ops, state initialisers).
given_anchor: Option<Span>v0.26: where the add-capability fix synthesises an absent given
clause — the handler’s return type (the clause follows it). None
where the clause lives elsewhere (a provider’s provides … given
line); the fix is then offered only when entries already exist.

§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);
