Struct Context 

pub struct Context(/* private fields */);

Implementations

impl Context

pub fn connect() -> Option<Self>

pub fn get_backend(&self) -> Result<LibsessionBackend>

pub fn get_session(&self) -> Result<Session>

Retrieves the session ID for the current process.

Errors

Returns Error::NotFound if the backend cannot resolve the session, or Error::InternalError if it returns a null session ID.

pub fn get_session_for_pid(&self, pid: i32) -> Result<Session>

Retrieves the session ID for a process.

Errors

Returns Error::NotFound if the backend cannot resolve the session, or Error::InternalError if it returns a null ID.

pub fn get_display_for_uid(&self, uid: u32) -> Result<Session>

pub fn list_sessions(&self) -> Result<Vec<Session>>

pub fn is_session_local(&self, session: &Session) -> Result<bool>

pub fn get_owner_uid_for_pid(&self, pid: i32) -> Result<u32>

pub fn get_user_state(&self, uid: u32) -> Result<LibsessionUserState>

pub fn get_session_uid(&self, session: &Session) -> Result<u32>

pub fn get_session_state( &self, session: &Session, ) -> Result<LibsessionSessionState>

pub fn is_session_active(&self, session: &Session) -> Result<bool>

pub unsafe fn set_log_fn(&self, callback: LibsessionLogFn) -> Result<()>

Sets the logging callback, or disables callbacks with None.

Errors

Returns an error if the underlying call fails.

Safety

The callback must remain callable until replaced or this context is dropped. It must not unwind or access this context reentrantly. The message pointer is valid only during the callback; it must not be retained or freed.

pub fn set_log_level(&self, level: LibsessionLogLevel) -> Result<()>

Sets the logging level. Off disables logging.

Errors

Returns an error if the underlying call fails.

pub fn get_log_level(&self) -> LibsessionLogLevel

Retrieves the current logging level.

pub fn get_monitor(&mut self) -> Result<Monitor>

Creates a monitor for session changes.

Errors

Returns Error::Unavailable if the backend cannot create a monitor.

Trait Implementations

impl Drop for Context

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.
