Struct Metadata

Source 
pub struct Metadata<'a> { /* private fields */ }
Available on crate feature component only.
Expand description

Metadata describing a metric.

All metrics have the following metadata:

  • A target, a string that categorizes part of the system where metric originates from. The `metrics`` macros default to using the module path where the metric originate as the target, but it may be overridden.
  • A level, specifying the verbosity the metric is emitted at.

In addition, the following optional metadata describing the source code location where the metric originated from may be provided:

  • The module path of the source code location where the metric event originated.

Metadata usage is exporter-specific, and may be ignored entirely. See the documentation of the specific exporter being used for more information.

Implementations§

Source§

impl<'a> Metadata<'a>

Source

pub const fn new( target: &'a str, level: Level, module_path: Option<&'a str>, ) -> Metadata<'a>

Constructs a new Metadata.

Source

pub fn level(&self) -> &Level

Returns the verbosity level of the metric.

Source

pub fn target(&self) -> &'a str

Returns the target of the metric.

This specifies the part of the system where the metric originates from. Typically, this is the module path where the metric originated from, but can be overridden when registering a metric.

Source

pub fn module_path(&self) -> Option<&'a str>

Returns the module path of the metric.

This specifies the module where the metric originates from, or None if the module path is unknown.
