Struct TailReader 

pub struct TailReader { /* private fields */ }

Incrementally reads new lines from a JSONL file.

Tracks the file position so that subsequent calls to read_new() return only lines appended since the last read.

Implementations

impl TailReader

pub fn new(path: &Path) -> Self

pub fn from_end(path: &Path) -> Self

Create a TailReader starting from the end of the current file.

pub fn read_new(&mut self) -> Vec<MetricRecord>

Read all new lines since the last read.
