Struct ZrecReader

Source

pub struct ZrecReader<R: BufRead> { /* private fields */ }

Expand description

A .zrec reader over any buffered byte source: header up front, then one item per line — bounded memory, like the writer.

Implementations§

Source §

impl<R: BufRead> ZrecReader<R>

Source

pub fn new(source: R) -> Result<Self>

Parse the header line. A file without one is not a .zrec — plain ndjson pipes replay through zenctl pub --from ndjson, which needs no base contract because the operator is the pacing.

Source

pub fn next(&mut self) -> Option<Result<ZrecItem, String>>

The next item, or Err naming the line and the reason — a malformed row is counted by the caller, never silently skipped (crate::tape::ingest’s rule). None ends the file.
