pub struct TransactionBuilder<'db> { /* private fields */ }Expand description
Builds a transaction with a specific isolation level.
Created by Database::transaction_with.
Implementations§
Source§impl<'db> TransactionBuilder<'db>
impl<'db> TransactionBuilder<'db>
Sourcepub fn immediate(self) -> Self
pub fn immediate(self) -> Self
Uses BEGIN IMMEDIATE, acquiring a write lock before any statement runs.
Sourcepub fn read_uncommitted(self) -> Self
pub fn read_uncommitted(self) -> Self
Requests the standard SQL READ UNCOMMITTED isolation level.
Sourcepub fn read_committed(self) -> Self
pub fn read_committed(self) -> Self
Requests the standard SQL READ COMMITTED isolation level.
Sourcepub fn repeatable_read(self) -> Self
pub fn repeatable_read(self) -> Self
Requests the standard SQL REPEATABLE READ isolation level.
Sourcepub fn serializable(self) -> Self
pub fn serializable(self) -> Self
Requests the standard SQL SERIALIZABLE isolation level (the strictest).
Sourcepub async fn begin(self) -> Result<Transaction>
pub async fn begin(self) -> Result<Transaction>
Opens the transaction with the configured isolation level.
§Errors
Returns an error if no connection is available or the BEGIN statement
fails (for example, BEGIN EXCLUSIVE when another connection holds a
lock and the busy timeout expires).

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>
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);
