Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

url_scheme: bool

Capture url.scheme as a span attribute.

Opt-In per the OTel HTTP semantic conventions.

request_body_size: bool

Capture http.request.body.size as a span attribute (actual bytes sent).

Opt-In per the OTel HTTP semantic conventions.

response_body_size: bool

Capture http.response.body.size as a span attribute (actual bytes received).

Opt-In per the OTel HTTP semantic conventions.

user_agent: bool

Capture user_agent.original from the outgoing User-Agent request header.

Opt-In per the OTel HTTP semantic conventions.

network_transport: bool

Capture network.transport as a span attribute. Always "tcp" for HTTP/1.1 and HTTP/2.

Opt-In per the OTel HTTP semantic conventions.

network_local_address: Option<String>

Static network.local.address span attribute: the outbound IP address of this service (e.g. "192.168.1.10"). Opt-In per the OTel HTTP semantic conventions.

network_local_port: Option<u16>

Static network.local.port span attribute: the source port this service binds to, if fixed. Opt-In per the OTel HTTP semantic conventions.

request_headers: Vec<HeaderName>

HTTP request header names to capture as span attributes (case-insensitive).

Each header x-foo becomes http.request.header.x-foo with a string-array value. Opt-In per the OTel HTTP semantic conventions.

response_headers: Vec<HeaderName>

HTTP response header names to capture as span attributes (case-insensitive).

Each header x-foo becomes http.response.header.x-foo with a string-array value. Opt-In per the OTel HTTP semantic conventions.
