s and trace Span
attributes.
Methods
impl Key
[src]
pub fn new<S: Into<Cow<'static, str>>>(value: S) -> Self
[src]
Create a new Key
.
pub fn bool(&self, value: bool) -> KeyValue
[src]
Create a KeyValue
pair for bool
values.
pub fn i64(&self, value: i64) -> KeyValue
[src]
Create a KeyValue
pair for i64
values.
pub fn u64(&self, value: u64) -> KeyValue
[src]
Create a KeyValue
pair for u64
values.
pub fn f64(&self, value: f64) -> KeyValue
[src]
Create a KeyValue
pair for f64
values.
pub fn string<S: Into<String>>(&self, value: S) -> KeyValue
[src]
Create a KeyValue
pair for Into<String>
values.
pub fn bytes(&self, value: Vec<u8>) -> KeyValue
[src]
Create a KeyValue
pair for byte arrays.
pub fn inner(&self) -> &Cow<'static, str>
[src]
Returns a reference to the key's Cow
type for use in LabelSet
s.
pub fn into_inner(self) -> Cow<'static, str>
[src]
Returns the inner Cow
type.
