Expand description

Abstraction over the header/metadata that works for http/grpc transport

Implemented for rama_http::HeaderMap (HTTP exporter) and crate::metadata::MetadataMap (gRPC exporter).

Required Methods§

fn merge(&mut self, other: Self)

Merge other into self, with other entries winning on conflict.

fn from_env( raw: &str, var: &'static str, ) -> Result<Self, OtelExporterConfigError>

Parse an OTEL_EXPORTER_OTLP_*_HEADERS env var value into a header bag. var is the env var name.

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.
