Struct ProxyJob 

pub struct ProxyJob { /* private fields */ }

A handle to a running background proxy generation job.

Created by ProxyGenerator::generate_async. Use progress for non-blocking progress polling and wait to block until the job completes.

Implementations

impl ProxyJob

pub fn progress(&self) -> f64

Current progress in the range 0.0..=1.0.

Reads an AtomicU32 — non-blocking and safe to call from any thread. Returns 0.0 when the source container does not report a frame count or before the first frame is encoded.

pub fn is_done(&self) -> bool

Returns true if the background thread has finished (success or error).

Non-blocking — does not consume the job.

pub fn wait(self) -> Result<PathBuf, PreviewError>

Block until proxy generation completes and return the output path.

Errors

Returns PreviewError if proxy generation failed or if the background thread panicked (surfaced as PreviewError::Ffmpeg { code: 0 }).
