Struct ServerSpan 

pub struct ServerSpan {

    pub ctx: TraceContext,
    pub method: String,
    pub method_original: Option<String>,
    pub url_path: String,
    pub url_query: Option<String>,
    pub url_scheme: String,
    pub status_code: u16,
    pub client_address: Option<String>,
    pub server_address: Option<String>,
    pub user_agent: Option<String>,
    pub protocol_version: Option<String>,
    pub outcome: String,
    pub request_id: String,
    pub start_unix_nano: u128,
    pub end_unix_nano: u128,
}

One proxied HTTP request, rendered as an OpenTelemetry SERVER span.

Attribute names follow the current stable HTTP semantic conventions, which renamed nearly all of them (http.method became http.request.method, http.url became url.*). Getting these wrong is not cosmetic: every backend normalizes on the stable names, so an old-name span is dropped from latency and error panels rather than being merely oddly labelled.

Fields

ctx: TraceContext

method: String

The method, or _OTHER when it is not one of the known set (semconv requires that).

method_original: Option<String>

Set only when method was replaced by _OTHER.

url_path: String

url_query: Option<String>

The query string, already sanitised by crate::accesslog::sanitize_target. None when the request carried none.

This is the one place the HTTP semconv is deliberately not followed to the letter. The spec wants the query as received; this proxy redacts credential-shaped values everywhere else it writes them, and a span is shipped to the same class of destination as an access log. Sending the raw query here would reintroduce, in traces, exactly the leak the access log was built to prevent.

url_scheme: String

status_code: u16

client_address: Option<String>

server_address: Option<String>

user_agent: Option<String>

protocol_version: Option<String>

outcome: String

EdgeGuard’s own verdict (proxied, rate_limited, waf_blocked, …). Not a semconv attribute, so it is namespaced — it says WHY a request ended as it did, which the status code alone does not.

request_id: String

start_unix_nano: u128

end_unix_nano: u128

Implementations

impl ServerSpan

pub fn normalize_method(method: &str) -> (String, Option<String>)

Methods the semantic conventions define. Anything else must be reported as _OTHER with the original in http.request.method_original, so an attacker cannot create unbounded label cardinality by inventing methods.

Trait Implementations

impl Clone for ServerSpan

fn clone(&self) -> ServerSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServerSpan

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

Formats the value using the given formatter.
