pub struct JsonTextPath { /* private fields */ }Expand description
Left-hand operand of a json_get_text filter — chain a comparison
method (.eq, .lt, .is_null, …) to produce a FilterExpr.
Implementations§
Source§impl JsonTextPath
impl JsonTextPath
pub fn eq<V>(self, value: V) -> FilterExprwhere
V: IntoSqlValue,
pub fn ne<V>(self, value: V) -> FilterExprwhere
V: IntoSqlValue,
pub fn lt<V>(self, value: V) -> FilterExprwhere
V: IntoSqlValue,
pub fn lte<V>(self, value: V) -> FilterExprwhere
V: IntoSqlValue,
pub fn gt<V>(self, value: V) -> FilterExprwhere
V: IntoSqlValue,
pub fn gte<V>(self, value: V) -> FilterExprwhere
V: IntoSqlValue,
Sourcepub fn is_null(self) -> FilterExpr
pub fn is_null(self) -> FilterExpr
col ->> 'key' IS NULL — the JSON document either lacks the
key, or stores it as JSON null. (PG and SQLite agree here.)
Sourcepub fn is_not_null(self) -> FilterExpr
pub fn is_not_null(self) -> FilterExpr
col ->> 'key' IS NOT NULL — the JSON document has the key
with a non-null primitive value. Note: a PG ? test (use
super::field_ref::FieldRef::json_has_key) treats JSON null
as a present key where this method does not.

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().

painted.white();Source§fn bright_black(&self) -> 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().

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.

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);
