Struct FlagPoller 

pub struct FlagPoller { /* private fields */ }

Synchronous poller for feature flag definitions.

Runs a background thread that periodically fetches flag definitions from the PostHog API and updates the shared cache. Use this for blocking/sync applications. With the async-client feature enabled, use AsyncFlagPoller for async applications instead.

Implementations

impl FlagPoller

pub fn new(config: LocalEvaluationConfig, cache: FlagCache) -> Self

Create a synchronous flag definition poller.

Parameters

• config: Credentials, host, polling interval, and request timeout.
• cache: Shared cache updated by the poller.

pub fn start(&mut self)

Start the polling thread.

Performs an initial synchronous load, then refreshes definitions in the background until FlagPoller::stop is called or the poller is dropped.

pub fn load_flags(&self) -> Result<(), Error>

Load flags synchronously and update the cache once.

Errors

Returns Error::Connection for request failures or non-success HTTP statuses, and Error::Serialization when the response cannot be parsed.

pub fn stop(&mut self)

Stop the polling thread and wait for it to exit.

Trait Implementations

impl Drop for FlagPoller

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
