Implementations§

impl<T> NullableStrCol<T>
pub const fn new(name: &'static str) -> Self
Sourcepub fn eq<S: Into<String>>(&self, val: S) -> Predicate<T>
pub fn eq<S: Into<String>>(&self, val: S) -> Predicate<T>
SQL =. NULL rows are excluded by SQL’s NULL semantics.
Sourcepub fn ne<S: Into<String>>(&self, val: S) -> Predicate<T>
pub fn ne<S: Into<String>>(&self, val: S) -> Predicate<T>
SQL <>. NULL rows are excluded by SQL’s NULL semantics.
Sourcepub fn ilike<S: Into<String>>(&self, pattern: S) -> Predicate<T>
pub fn ilike<S: Into<String>>(&self, pattern: S) -> Predicate<T>
Case-insensitive LIKE via UPPER(col) LIKE UPPER(pattern).
Sourcepub fn contains<S: Into<String>>(&self, substring: S) -> Predicate<T>
pub fn contains<S: Into<String>>(&self, substring: S) -> Predicate<T>
SQL LIKE '%val%' substring containment.
Sourcepub fn icontains<S: Into<String>>(&self, substring: S) -> Predicate<T>
pub fn icontains<S: Into<String>>(&self, substring: S) -> Predicate<T>

Sourcepub fn startswith<S: Into<String>>(&self, prefix: S) -> Predicate<T>
pub fn startswith<S: Into<String>>(&self, prefix: S) -> Predicate<T>
SQL LIKE 'val%' — prefix match. Mirrors the REST filter
parser’s __startswith lookup.
Sourcepub fn istartswith<S: Into<String>>(&self, prefix: S) -> Predicate<T>
pub fn istartswith<S: Into<String>>(&self, prefix: S) -> Predicate<T>
Case-insensitive prefix match via UPPER(col) LIKE UPPER('val%').
Sourcepub fn is_not_null(&self) -> Predicate<T>
pub fn is_not_null(&self) -> Predicate<T>
SQL IS NOT NULL.

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().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§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();Source§fn on_primary(&self) -> Painted<&T>

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().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§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();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.
fn clear(&self) -> Painted<&T>
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);
