> This function is defined in the [**secrets**](../modules/secrets) module.

Register a custom resolver for a source name (e.g. `vault`).

Custom sources extend :data:`SecretRef` beyond the built-in three; the
`SecretRef` validation still applies, so use this together with a
`provider` hint or by resolving `exec`-style commands.

## Signature
