Struct zng_ext_single_instance::AppInstanceArgs

pub struct AppInstanceArgs {
    pub timestamp: DInstant,
    pub args: Box<[Txt]>,
    pub count: usize,
    /* private fields */
}

Arguments for APP_INSTANCE_EVENT.

Fields

timestamp: DInstant

Instant the event happened.

args: Box<[Txt]>

Arguments the app instance was started with.

See std::env::args for more details.

count: usize

Instance count. Is zero for the current process, in single instance mode increments for each subsequent attempt to instantiate the app.

Implementations

impl AppInstanceArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, args: impl Into<Box<[Txt]>>, count: impl Into<usize>, ) -> Self

New args from values that convert into the argument types.

pub fn now(args: impl Into<Box<[Txt]>>, count: impl Into<usize>) -> Self

Arguments for event that happened now (INSTANT.now).

impl AppInstanceArgs

pub fn is_current(&self) -> bool

If the arguments are for the currently executing process (main).

This is only true once, on the first event on startup.

Trait Implementations

impl AnyEventArgs for AppInstanceArgs

fn clone_any(&self) -> Box<dyn AnyEventArgs>

Clone the event into a type erased box.

fn as_any(&self) -> &dyn Any

Access to dyn Any methods.

fn timestamp(&self) -> DInstant

Gets the instant this event happened.

fn delivery_list(&self, _list: &mut UpdateDeliveryList)

Insert all targets of this event on the UpdateDeliveryList.

fn propagation(&self) -> &EventPropagationHandle

Propagation handle associated with this event instance.

impl Clone for AppInstanceArgs

fn clone(&self) -> AppInstanceArgs

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AppInstanceArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl EventArgs for AppInstanceArgs

fn handle<F, R>(&self, handler: F) -> Option<R>

where F: FnOnce(&Self) -> R,

Calls handler and stops propagation if propagation is still allowed.
