Struct FrameReader

Source

pub struct FrameReader { /* private fields */ }

Expand description

State for reading Perfetto IPC frames.

Each frame is composed of a 32 bit length in little endian, followed by the proto-encoded message. This state handles reads that only include partial messages.

Implementations§

Source §

impl FrameReader

Source

pub fn new(file: FileHandle) -> Self

Source

pub fn next_frame_blocking<L>( &mut self, locked: &mut Locked<L>, current_task: &CurrentTask, ) -> Result<IpcFrame, IpcReadError>
where L: LockEqualOrBefore<FileOpsCore>,

Repeatedly reads from the specified file until a full message is available.
