Struct SeekableAsyncFileMetrics

pub struct SeekableAsyncFileMetrics { /* private fields */ }

Metrics populated by a SeekableAsyncFile. There should be exactly one per SeekableAsyncFile; don’t share between multiple SeekableAsyncFile values.

To initalise, use SeekableAsyncFileMetrics::default(). The values can be accessed via the thread-safe getter methods.

Implementations

impl SeekableAsyncFileMetrics
