pub struct DirectoryEndpointResolver { /* private fields */ }Expand description
Adapts the service DirectoryClient into the contract-layer
EndpointResolver consumed by DirectoryResolvingClient.
Keeps toolkit-contract free of a dependency on the directory SDK: the
adapter lives here in toolkit, which already owns DirectoryClient.
Successful resolutions are memoized for a short TTL (Self::TTL) so a
per-call resolving client does not incur a directory round-trip on every
business call (the OoP directory is a network hop). Only Ok(Some(uri)) is
cached; Ok(None) / Err always re-resolve. The TTL is deliberately short
so endpoint churn self-heals within ~TTL.
Implementations§
Source§impl DirectoryEndpointResolver
impl DirectoryEndpointResolver
Sourcepub const TTL: Duration
pub const TTL: Duration
Memoization window for successful resolutions.
Public because it bounds observable behaviour: a provider that moves is followed within roughly this window, not instantly, since the cache holds only successes and is not invalidated by a failed call.
Sourcepub fn new(client: Arc<dyn DirectoryClient>) -> Self
pub fn new(client: Arc<dyn DirectoryClient>) -> Self
Wrap a DirectoryClient with a short-TTL resolution cache.

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>

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;

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

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
