diesel-connection

Static diesel r2d2 connection pooling.

DATABASE_URL env sets postgres database url within connection manager MAX_DB_CONNECTIONS env sets max postgres connections within connection pool

This library uses booter::boot() to initialize.

The tracing feature flag substitutes connections instrumented with opentelemetry. See diesel-tracing for details.
