Crate apollo_federation

Usage

This crate is internal to Apollo Router and not intended to be used directly.

Crate versioning

The apollo-federation crate does not adhere to Semantic Versioning. Any version may have breaking API changes, as this API is expected to only be used by apollo-router. Instead, the version number matches exactly that of the apollo-router crate version using it.

This version number is not that of the Apollo Federation specification being implemented. See Router documentation for which Federation versions are supported by which Router versions.
