Struct mz_secrets::SecretsReader

pub struct SecretsReader { /* private fields */ }

Securely reads secrets that are managed by a SecretsController.

Does not provide access to create, update, or delete the secrets within.

Implementations

impl SecretsReader

pub fn new(config: SecretsReaderConfig) -> Self

pub async fn read(&self, id: GlobalId) -> Result<Vec<u8>, Error>

Returns the contents of a secret identified by GlobalId

This read will return a complete version of the secret. It will not return, e.g., one block from v1 and another from v2.

• On Linux / OSX filesystems, File::open will hold a handle open so that even if the file is deleted, we still continue to read from it. This means a SecretOp::Delete followed by a SecretOp::Ensure can never “swap out” data mid-read_to_end.
• We do not allow editing secrets which would expose us to this issue.

(N.B. Were we ever to run with Windows / NTFS, this would also work properly and mid-read edits would be disallowed)

pub async fn read_string(&self, id: GlobalId) -> Result<String>

pub fn canonical_path(&self, id: GlobalId) -> Result<PathBuf, Error>

Returns the path of the secret consisting of a configured base path and the GlobalId
