CODE_COLUMN_NUMBER: Final = "code.column.number"
"""
The column number in `code.file.path` best representing the operation. It SHOULD point within the code unit named in `code.function.name`.
"""

CODE_FILE_PATH: Final = "code.file.path"
"""
The source code file name that identifies the code unit as uniquely as possible (preferably an absolute file path).

Deprecated: Replaced by `code.file.path`.

CODE_FUNCTION: Final = "code.function"

Deprecated: Replaced by `code.function.name`.
"""

CODE_FUNCTION_NAME: Final = "code.function.name"
"""
The method or function fully-qualified name without arguments. The value should fit the natural representation of the language runtime, which is also likely the same used within `code.stacktrace` attribute value.
Note: Values and format depends on each language runtime, thus it is impossible to provide an exhaustive list of examples.
The values are usually the same (or prefixes of) the ones found in native stack trace representation stored in
`code.stacktrace` without information on arguments.

Examples:

* Java method: `com.example.MyHttpService.serveRequest`
* Java anonymous class method: `com.mycompany.Main$1.myMethod`
* Java lambda method: `com.mycompany.Main$$Lambda/0x0000748ae4149c00.myMethod`
* PHP function: `GuzzleHttp\\Client::transfer
* Go function: `github.com/my/repo/pkg.foo.func5`
* Elixir: `OpenTelemetry.Ctx.new`
* Erlang: `opentelemetry_ctx:new`
* Rust: `playground::my_module::my_cool_func`
* C function: `fopen`.

CODE_LINENO: Final = "code.lineno"

CODE_NAMESPACE: Final = "code.namespace"

Deprecated: Value should be included in `code.function.name` which is expected to be a fully-qualified name.
"""

CODE_STACKTRACE: Final = "code.stacktrace"
"""
A stacktrace as a string in the natural representation for the language runtime. The representation is identical to [`exception.stacktrace`](/docs/exceptions/exceptions-spans.md#stacktrace-representation).
