Types

variant error

An error type that encapsulates the different errors that can occur fetching configuration values.

Variant Cases

• upstream: string

  This indicates an error from an "upstream" config source. As this could be almost _anything_ (such as Vault, Kubernetes ConfigMaps, KeyValue buckets, etc), the error message is a string.

• io: string

  This indicates an error from an I/O operation. As this could be almost _anything_ (such as a file read, network connection, etc), the error message is a string. Depending on how this ends up being consumed, we may consider moving this to use the `wasi:io/error` type instead. For simplicity right now in supporting multiple implementations, it is being left as a string.
