Struct AntWriter 

Source 
pub struct AntWriter<W: Write> { /* private fields */ }
Expand description

Streaming .ant writer: records in, zstd-framed NDJSON out. Call AntWriter::finish to emit the trailer and flush.

Implementations§

Source§

impl<W: Write> AntWriter<W>

Source

pub fn new(out: W, manifest: Manifest, level: i32) -> Result<Self, AntError>

Compression level 0 = zstd default (currently 3). Levels up to 19 trade speed for size; text-heavy evidence compresses 5-10x at the default already.

Source

pub fn write(&mut self, rec: AntRecord) -> Result<(), AntError>

Source

pub fn counts(&self) -> &Counts

Records written so far (excluding manifest/trailer).

Source

pub fn finish(self) -> Result<W, AntError>

Emit the trailer (counts + sha256 of everything before it) and finish the zstd frame. Returns the inner writer.
