Struct PlayerSession 

pub struct PlayerSession {
    app: Application,
    inner: Mutex<Option<Inner>>,
}

Tauri shell’s player state. Shared via tauri::State<PlayerSession>.

Fields

app: Application

inner: Mutex<Option<Inner>>

Implementations

impl PlayerSession

pub fn new() -> Self

Boot the session — builds a [wisp::application::Application] up-front so subsequent open calls don’t pay device-init latency.

Panics

Panics if no compatible GPU adapter is available. The recorder can’t function without one, so failing fast is preferable to surfacing a deferred error through the IPC layer.

pub fn open(&self, path: &Path) -> Result<PlayerStatus, String>

Open a video file. Replaces any currently-loaded session.

Returns the fresh PlayerStatus (the new session begins in SessionState::Paused).

Errors

Returns an error string if the file can’t be opened (missing, unreadable, unsupported codec). The error is surfaced to the webview so the UI can show a toast.

pub fn play(&self)

Transition to SessionState::Playing. No-op when empty or already playing.

pub fn pause(&self)

Transition to SessionState::Paused. No-op when empty.

pub fn tick(&self) -> u32

Drive the player by the wallclock delta since the last tick.

Returns the number of frames the player uploaded. 0 when the session is empty, paused, ended, or no new frame was due.

pub fn status(&self) -> PlayerStatus

Snapshot of the current status. Cheap — no decoding work.

Trait Implementations

impl Default for PlayerSession

fn default() -> Self

Returns the “default value” for a type.
