Struct KvEngine 

pub struct KvEngine;

Versioned static KV engine (kv-v2-style): every write creates a new version, delete soft-deletes the current version without erasing history, read always returns the latest non-deleted version.

Implementations

impl KvEngine

pub fn new() -> Self

Trait Implementations

impl Default for KvEngine

fn default() -> Self

Returns the “default value” for a type.

impl SecretsEngine for KvEngine

fn doc(&self) -> EngineDoc

Self-documentation. Every engine must answer this — an engine that cannot say what its credentials are worth has no business minting them.

Dynamic-secret engines (e.g. Postgres) override these; static engines (e.g. KV) inherit the default Unsupported.
