Enum SpanKind 

#[repr(u32)]
pub enum SpanKind {
    Internal = 1,
    Server = 2,
    Client = 3,
    Producer = 4,
    Consumer = 5,
}

OpenTelemetry SpanKind values, encoded on the wire as a uint32. Unset or unrecognized kinds default to SpanKind::Internal.

Variants

Internal = 1

Server = 2

Client = 3

Producer = 4

Consumer = 5
