Foreign-language persistence contract; implement every method in Node or Python.

UniFFI callback interfaces do not inherit Rust default method bodies. A store must explicitly implement locking and may implement prepare_write as a no-op when writes need no preflight. Credential JSON can contain refresh tokens.

Required Methods

fn load<'life0, 'async_trait>( &'life0 self, profile: String, ) -> Pin<Box<dyn Future<Output = BindingResult<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Load credential JSON, returning None when the key does not exist.

fn prepare_write<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = BindingResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Check write readiness before a provider rotates a refresh token.

fn save<'life0, 'async_trait>( &'life0 self, profile: String, token: String, ) -> Pin<Box<dyn Future<Output = BindingResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Persist credential JSON without discarding unrelated keys.

fn remove<'life0, 'async_trait>( &'life0 self, profile: String, ) -> Pin<Box<dyn Future<Output = BindingResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Delete only the specified credential.

fn acquire_lock<'life0, 'async_trait>( &'life0 self, profile: String, timeout_millis: u64, ) -> Pin<Box<dyn Future<Output = BindingResult<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Acquire an exclusive refresh lease or fail within the timeout.

fn release_lock<'life0, 'async_trait>( &'life0 self, lease: String, ) -> Pin<Box<dyn Future<Output = BindingResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Release the lease returned by acquire_lock.

fn name(&self) -> String

Return a human-readable backend identifier.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
