Struct Metadata

pub struct Metadata<'a> { /* private fields */ }
Expand description

Metadata describing a metric event. This provides additional context to Recorder, allowing for fine-grained filtering.

Contains the following:

  • A target, specifying the part of the system where the metric event occurred. When initialized via the [metrics macro], and left unspecified, this defaults to the module path the macro was invoked from.
  • A level, specifying the verbosity the metric event is emitted at.
  • An optional module_path, specifying the the module path the metric event was emitted from.

Implementations§

§

impl<'a> Metadata<'a>

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

Constructs a new Metadata.

pub fn level(&self) -> &Level

Returns the verbosity level of the metric event.

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

Returns the target of the metric event. This specifies the part of the system where the event occurred.

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