Struct FileCredentialProvider 

pub struct FileCredentialProvider { /* private fields */ }

Reads credentials from a JSON file (e.g. ~/.quantrs/credentials.json).

The file must contain a flat JSON object mapping string keys to string values. On Unix systems the file must have mode 0o600; looser permissions are rejected.

Example file

{
  "IBM_TOKEN": "my-ibm-token",
  "AWS_SECRET": "my-aws-secret"
}
