pub struct Recorder { /* private fields */ }otel only.Expand description
The instruments one configuration records into.
Cheap to build and cheap to hold: an instrument from a provider nobody installed does nothing at all.
Implementations§
Source§impl Recorder
impl Recorder
Sourcepub fn new(name: &'static str) -> Self
pub fn new(name: &'static str) -> Self
Instruments for the configuration called name, from the global
meter.
name is the label every sample carries, so it is the caller’s to
choose — usually the configuration type’s name. It must be bounded:
a name derived from a request, a tenant or a path is a cardinality
incident waiting for a busy afternoon.
Sourcepub fn with_meter(name: &'static str, meter: &Meter) -> Self
pub fn with_meter(name: &'static str, meter: &Meter) -> Self
new, against a meter the caller already has.
Sourcepub fn installed<T>(&self, event: &ReloadEvent<T>, fingerprint: Option<&str>)
pub fn installed<T>(&self, event: &ReloadEvent<T>, fingerprint: Option<&str>)
Records an install.
The reason and the fingerprint ride along as attributes: the first is one of five strings, the second is a digest with secrets masked. Both are bounded, and neither can carry a value.
Sourcepub fn refused(&self, error: &Error)
pub fn refused(&self, error: &Error)
Records a reload that installed nothing.
The error’s kind and not its message: a message names the file or the key that failed, which is unbounded and, in the case of a parse failure, is frequently the line holding the password.
Sourcepub fn attributes(&self, status: &ConfigStatus) -> Vec<KeyValue>
pub fn attributes(&self, status: &ConfigStatus) -> Vec<KeyValue>
The attributes a caller’s own instrument should carry to line up with these.
For the gauges this module does not own — health, staleness, whatever an application already computes — so that a dashboard can join them without a translation table.

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;

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);
