pub struct ExtScalar<'a> { /* private fields */ }Expand description
A scalar value representing an extension type.
Extension types allow wrapping a storage type with custom semantics.
Implementations§
Source§impl<'a> ExtScalar<'a>
impl<'a> ExtScalar<'a>
Sourcepub fn try_new(
dtype: &'a DType,
value: Option<&'a ScalarValue>,
) -> VortexResult<Self>
pub fn try_new( dtype: &'a DType, value: Option<&'a ScalarValue>, ) -> VortexResult<Self>
Creates a new extension scalar from a data type and scalar value.
§Errors
Returns an error if the data type is not an extension type.
Sourcepub fn to_storage_scalar(&self) -> Scalar
pub fn to_storage_scalar(&self) -> Scalar
Returns the storage scalar of the extension scalar.
Sourcepub fn ext_dtype(&self) -> &'a ExtDTypeRef
pub fn ext_dtype(&self) -> &'a ExtDTypeRef

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

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().

Enables the yansi Quirk value.

builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};

👎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.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
