Source§impl HdbReturnValue
impl HdbReturnValue
Sourcepub fn into_result_set(self) -> Result<ResultSet, HdbError>
pub fn into_result_set(self) -> Result<ResultSet, HdbError>

§Errors
HdbError::Evaluation for other variants than HdbReturnValue::ResultSet.
Sourcepub fn into_affected_rows(self) -> Result<Vec<usize>, HdbError>
pub fn into_affected_rows(self) -> Result<Vec<usize>, HdbError>
Turns itself into a Vector of numbers (each number representing a number of affected rows).
§Errors
HdbError::Evaluation for other variants than HdbReturnValue::AffectedRows.
Sourcepub fn into_output_parameters(self) -> Result<OutputParameters, HdbError>
pub fn into_output_parameters(self) -> Result<OutputParameters, HdbError>

§Errors
HdbError::Evaluation for other variants than HdbReturnValue::OutputParameters.
Sourcepub fn into_success(self) -> Result<(), HdbError>
pub fn into_success(self) -> Result<(), HdbError>
Turns itself into (), if the statement had returned successfully.
§Errors
HdbError::Evaluation for other variants of HdbReturnValue.
Sourcepub fn is_success(&self) -> bool
pub fn is_success(&self) -> bool
Returns true if the statement had returned successfully.

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().

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>
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>
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);
