Struct ServerTimingBuilder 

pub struct ServerTimingBuilder { /* private fields */ }

Builder for constructing Server-Timing headers with multiple metrics.

Collects multiple timing entries and formats them as a single header value.

Example

let timing = ServerTimingBuilder::new()
    .add("total", 150.5)
    .add_with_desc("db", 42.0, "Database queries")
    .add_with_desc("cache", 5.0, "Cache lookup")
    .build();

// Result: "total;dur=150.500, db;dur=42.000;desc=\"Database queries\", cache;dur=5.000;desc=\"Cache lookup\""
