}Expand description
One byte-range in a rendered prompt mapped back to its source
template. Foundation for the prompt-provenance UX (burin-code #93):
hover a chunk of the live prompt in the debugger and jump to the
.harn.prompt line that produced it.
output_start / output_end are byte offsets into the rendered
string. template_line / template_col are 1-based positions in
the source template. bound_value carries a short preview of the
expression’s runtime value when it’s a scalar; omitted for
structural nodes (if/for/include) so callers don’t log a giant
dict display for a single {% for %}.
Fields§
§template_line: usize§template_col: usize§output_start: usize§output_end: usize§kind: PromptSpanKind§bound_value: Option<String>§parent_span: Option<Box<PromptSourceSpan>>When the span was rendered from inside an include (possibly
transitively), this points at the including call’s span in the
parent template. Chained boxes let the IDE walk A → B → C
cross-template breadcrumbs when a deep render spans three
files. None for top-level spans.
template_uri: StringTemplate URI for the file that authored this span. Top-level
spans carry the root render’s template uri; included-child
spans carry the included file’s uri so breadcrumb navigation
can open the right file when the user clicks through the
parent_span chain. Defaults to empty string for callers that
don’t plumb it through.

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().

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().

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);
