Trait TracerExt 

pub trait TracerExt {
    // Required method
    fn trace_stable_enum_type<T>(&mut self, samples: &Samples) -> Result<Format>
       where T: StableEnumTrace;
}

Extension methods on Tracer for tracing enums whose variant tags are not contiguous starting at zero.

The standard Tracer::trace_type discovers an enum’s variants by probing 0, 1, 2, … until each u32 index has been seen. With Keccak-derived stable tags those indices are not consecutive (they live in [2^27, 2^28)), so probing never terminates. This trait delegates to the enum’s StableEnumTrace impl, which drives tracing variant-by-variant via the enum’s Serialize impl.

Required Methods

fn trace_stable_enum_type<T>(&mut self, samples: &Samples) -> Result<Format>

where T: StableEnumTrace,

Trace every variant of a stable-tagged enum, returning the enum’s Format for use in Formats::operation, Formats::response, etc.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
