pub struct Loader { /* private fields */ }Expand description
Generic loader that manages concurrent loading of Loadable types.
Uses a semaphore to limit the number of concurrent load operations, preventing resource exhaustion while still allowing some parallelism.
This loader is not generic itself, but its load() method is generic,
allowing a single Loader instance to load different types and scopes.
Implementations§
Source§impl Loader
impl Loader
Sourcepub fn new(max_concurrent_loads: usize) -> Self
pub fn new(max_concurrent_loads: usize) -> Self
Creates a new Loader with a specified maximum number of concurrent loads.
§Arguments
max_concurrent_loads- Maximum number of load operations that can run concurrently
Sourcepub async fn load<T: Loadable<S>, S>(
&self,
spec: LoadSpec<T, S>,
scope: &S,
) -> StorageResult<LoadResult<T>>
pub async fn load<T: Loadable<S>, S>( &self, spec: LoadSpec<T, S>, scope: &S, ) -> StorageResult<LoadResult<T>>
Load a bucket from storage.
Acquires a semaphore permit to limit concurrent loads, then spawns an async task to perform the actual loading operation.
If the LoadSpec does not include metadata, a new load_id (UUID) will be generated and sequence_number will be set to 0.
Returns a LoadResult containing the loaded data and synchronization metadata.

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>

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.
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);
