pub struct Query { /* private fields */ }Expand description
A query builder for constructing and executing SQL queries.
This struct provides a fluent interface for building SQL queries with parameter binding, and methods to execute those queries or fetch their results.
Implementations§
Source§impl Query
impl Query
Sourcepub fn builder() -> QueryBuilder
pub fn builder() -> QueryBuilder
Creates a new QueryBuilder instance.
This is the entry point for constructing a new query using the builder pattern.
Sourcepub fn execute<'a>(
self,
connection: impl Into<ConnectionLike<'a>>,
) -> Result<u64, SdkError>
pub fn execute<'a>( self, connection: impl Into<ConnectionLike<'a>>, ) -> Result<u64, SdkError>
Executes the SQL query with the bound parameters.
This method sends the query to the database server and returns the number of rows affected. For INSERT, UPDATE, or DELETE statements, this represents the number of rows modified. For other statements, the meaning of the return value depends on the specific operation.
§Returns
The number of rows affected by the query, or an error message if the execution failed
Sourcepub fn fetch<'a>(
self,
connection: impl Into<ConnectionLike<'a>>,
) -> Result<impl Iterator<Item = ColumnIterator>, SdkError>
pub fn fetch<'a>( self, connection: impl Into<ConnectionLike<'a>>, ) -> Result<impl Iterator<Item = ColumnIterator>, SdkError>
Executes the SQL query and fetches all rows from the result.
This method sends the query to the database and returns all rows in the result set. It’s useful for SELECT queries where you want to process multiple results.
§Returns
A vector containing all rows in the result set, or an error message if the execution failed

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>
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> PolicyExt for Twhere
