pub struct VariantSlots {
pub core_storage: ArrayRef,
pub shredded: Option<ArrayRef>,
}Expand description
Slots for canonical variant storage.
A canonical variant array keeps the full variant value for every row in core_storage and may
carry a row-aligned, storage-agnostic shredded typed tree for selected paths.
core_storage is a logical DType::Variant array, not a specific physical encoding: it may be
chunked, constant, or otherwise encoded. Callers must use normal array operations instead of
assuming a particular slot layout. The shredded child may have any dtype; its dtype is recorded
during serialization and validated by normal child deserialization.
Fields§
§core_storage: ArrayRefThe logical variant storage that preserves the full value for every row.
shredded: Option<ArrayRef>The optional row-aligned typed shredded tree for selected variant paths.
This slot is Some only if the array was canonicalized and the shredded data
was pulled out of the underlying variant storage.

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};
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);Source§impl<T> Pipe for Twhere
