Struct opentelemetry::Key
source · pub struct Key(/* private fields */);
Expand description
The key part of attribute KeyValue pairs.
See the attribute naming spec for guidelines.
Implementations§
source§impl Key
impl Key
sourcepub fn new(value: impl Into<Key>) -> Self
pub fn new(value: impl Into<Key>) -> Self

.
§Examples
use opentelemetry::Key;
use std::sync::Arc;
let key1 = Key::new("my_static_str");
let key2 = Key::new(String::from("my_owned_string"));
let key3 = Key::new(Arc::from("my_ref_counted_str"));
sourcepub const fn from_static_str(value: &'static str) -> Self
pub const fn from_static_str(value: &'static str) -> Self
Create a new const Key
.
sourcepub fn string(self, value: impl Into<StringValue>) -> KeyValue
pub fn string(self, value: impl Into<StringValue>) -> KeyValue
Create a KeyValue
pair for string-like values.
