Struct RestartIndex

Source

pub struct RestartIndex {
    pub scan_data_offset: usize,
    pub interval_mcus: u32,
    pub segments: Vec<RestartSegment>,
}

Expand description

Restart-marker index for a single-scan JPEG stream.

The segment vector is derived from untrusted MCU geometry and can approach the shared host-allocation cap. Share this move-only owner behind Arc when multiple consumers need the same index.

Fields§

§scan_data_offset: usize

Absolute byte offset of the first entropy byte after the SOS header.

§interval_mcus: u32

Restart interval from DRI, in MCUs.

§segments: Vec<RestartSegment>

Restart-addressable scan segments in MCU order.
