Constant URL_EXTENSION 

pub const URL_EXTENSION: &'static str;

Available on crate features opentelemetry and semconv_experimental only.

The file extension extracted from the url.full, excluding the leading dot.

Notes

The file extension is only set if it exists, as not every url has a file extension. When the file name has multiple extensions example.tar.gz, only the last one should be captured gz, not tar.gz.

Examples

• "png"
• "gz"
