}Expand description
Configuration for the StorageService.
Controls operational parameters of the storage service layer that sits between the HTTP server and the storage backends.
Used in: Config::service

Fields§
§max_concurrency: u32Maximum number of concurrent backend operations.
This caps the total number of in-flight storage operations (reads, writes, deletes) across all requests. Operations that exceed the limit are rejected with HTTP 429.
§Default
concurrency_queue: u32Maximum number of requests that may wait for a concurrency permit.
When all max_concurrency execution slots are held, up to this many
additional requests will park and wait (for at most
concurrency_timeout) instead of being rejected immediately.
Requests beyond that are rejected with HTTP 429.
Sizing guidance: concurrency_queue ≈ permit_release_rate × acceptable_added_latency.
§Default
0
concurrency_timeout: DurationMaximum time a caller may wait for a concurrency permit.
Applies to both queued normal requests and bulk operations waiting for the bulk and execution semaphores.
§Default
1s
bulk_concurrency_pct: u32Percentage of max_concurrency available to bulk operations
(e.g. parallelized batch requests).
This sets a safe operating point: below this level there is little-to-no performance degradation, leaving room for more tasks to be admitted via the queue before rejection is necessary.
Clamped to 1..=100. At 100, bulk operations can use all execution slots. Lower values leave headroom for single-object requests.
§Default
60
background_queue: usizeMaximum number of deduplicated TTI renewals waiting for background processing.
Scheduling never waits for space. A renewal is dropped when this queue is full. Values below one are clamped to one.
§Default
1000
encryption: Option<EncryptionConfig>Persistent symmetric encryption keys.
Currently, the keys are used for encryption and decryption of session tokens of the Resumable Uploads API. If keys are not explicitly configured, session token encryption will use an ephemeral key generated at startup, which means that resumable upload sessions won’t work in a multi-instance deployment or survive a restart. Configure a persistent keyring in production.
Keys must contain exactly 32 raw bytes.

§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();§fn bright_black(&self) -> Painted<&T>

§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;

§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();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§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();§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 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);
