Struct CacheWriter 

pub struct CacheWriter { /* private fields */ }

Writes events to on-disk binary cache format.

Implementations

impl CacheWriter

pub fn new() -> Self

Create an empty cache writer.

pub fn push_event(&mut self, event: &Event)

Add one event to the writer buffer.

pub fn write_to_file(&self, path: &Path) -> Result<CacheStats>

Encode all buffered events and write them to path.

Parent directories are created automatically.

Errors

Returns an error if encoding or file I/O fails.

pub fn append_incremental( existing: &Path, new_events: &[Event], ) -> Result<CacheStats>

Append new_events to an existing cache file, rewriting the whole file.

If the cache file does not exist, this behaves like a normal write with just new_events.

Errors

Returns an error if decoding existing data, encoding, or file I/O fails.
