Enum Metatag

pub enum Metatag {
    Target,
}

Tag derived from metadata.

Unlike tags, metatags are not represented as strings and instead must be resolved from event metadata. This means that they may resolve to different text for different events.

Variants

Target

The location of a span or event.

The target is typically a module path, but this can be configured by a particular span or event when it is constructed.

Trait Implementations

impl Clone for Metatag

fn clone(&self) -> Metatag

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Metatag

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Metatag

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Metatag

fn eq(&self, other: &Metatag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
