Enum DescriptorSource 

#[non_exhaustive]
pub enum DescriptorSource {
    Protoc,
    Precompiled(PathBuf),
}

Source of the FileDescriptorSet. Spec 12 § 4.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Protoc

Invoke protoc (default). Requires it on PATH or via PROTOC env.

Precompiled(PathBuf)

Use a pre-built FDS file (skips protoc invocation).
