Struct SaveOptions 

pub struct SaveOptions {
    pub topic: Option<String>,
    pub colormap: Colormap,
    pub normalize: Option<bool>,
    pub format: Option<String>,
    pub compression: Compression,
    pub packet_compression: PacketCompression,
}

Options for the save_stream / save_frame writers — the symmetric mirror of LoadOptions. Most formats ignore every field; readers and writers agree on the rest.

Fields

topic: Option<String>

Rosbag topic to write the dvs_msgs/EventArray messages on (defaults to /davis/left/events, matching the reader).

colormap: Colormap

PNG frame export only: the colour map (default Colormap::Viridis).

normalize: Option<bool>

PNG frame export only: auto-contrast the field to its data range. None = true.

format: Option<String>

Overrides the format the extension implies. Two cases need it: writing E2VID’s layout to a .txt (which otherwise means eventcv’s own text format — .zip already implies it), and choosing between the two Prophesee .raw encodings with "evt2" / "evt3". None follows the extension.

compression: Compression

HDF5 only: how the event columns are filtered. Defaults to Compression::Gzip at level 4.

packet_compression: PacketCompression

AEDAT 4 only: how each packet body is compressed. Defaults to LZ4, which is what DV writes.

Implementations

impl SaveOptions

pub fn evt_version(&self) -> EvtVersion

The Prophesee .raw encoding format asks for, defaulting to EVT2.

EVT2 is the default because it is the encoding a reader can decode without carrying state across words, so a file eventcv writes stays the easiest thing for another tool to open; EVT3 is smaller and is chosen explicitly.

Trait Implementations

impl Clone for SaveOptions

fn clone(&self) -> SaveOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SaveOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SaveOptions

fn default() -> SaveOptions

Returns the “default value” for a type.
