impl DatabaseBackend for SqliteBackend
Source§fn supports(&self, feature: BackendFeature) -> bool
fn supports(&self, feature: BackendFeature) -> bool
SQLite feature catalogue. Source of truth: spec
docs/specs/05-backends-and-system-check.md §7.1. SQLite carries
the modern transactional features (RETURNING since 3.35, ON
CONFLICT since 3.24) and native BOOLEAN, but no array / hstore /
jsonb / full-text / network / native-UUID surface. UUIDs go
through TEXT instead; see map_type below.
Source§fn map_type(&self, ty: SqlType) -> ColumnType
fn map_type(&self, ty: SqlType) -> ColumnType
SQLite SqlType -> sea_query::ColumnType mapping. Source of
truth: spec 05-backends-and-system-check.md §7.1. Uuid lands
on Text because SQLite has no native UUID type, which is the
reason supports(UuidNative) reports false above.
Source§fn name(&self) -> &'static str
fn name(&self) -> &'static str
"postgres", "sqlite", etc. Used as
the matching key in FieldSpec::supported_backends, and shown
in system-check error messages.Source§fn map_column(&self, col: &Column) -> ColumnType
fn map_column(&self, col: &Column) -> ColumnType
max_length)
to its sea-query ColumnType. Default impl delegates to
map_type — backends that want to lift hints (Postgres
rendering Text + max_length=N as VARCHAR(N), for example)
override this. The migration engine prefers this over
map_type so the per-column attributes flow into DDL.Auto Trait Implementations§

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>
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);
