Struct Key
#[non_exhaustive]pub struct Key(/* private fields */);
Expand description
The key part of attribute KeyValue pairs.
See the attribute naming spec for guidelines.
Implementations§
§impl Key
impl Key
pub fn new(value: impl Into<Key>) -> Key
pub fn new(value: impl Into<Key>) -> Key
Create a new Key
.
§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"));
pub const fn from_static_str(value: &'static str) -> Key
pub const fn from_static_str(value: &'static str) -> Key
Create a new const Key
.
