Implementations

impl BarcFile

pub fn new<P>(path: P) -> BarcFilewhere
    P: AsRef<Path>,

Return new instance for the specified path, which may be an existing file, or one to be created when writer is opened.

pub fn writer(&self) -> Result<BarcWriter<'_>, BarcError>

Get a writer for this file, opening the file for write (and possibly creating it, or erroring) if this is the first time called. May block on the write lock, as only one BarcWriter instance is allowed.

pub fn reader(&self) -> Result<BarcReader, BarcError>

Get a reader for this file. Errors if the file does not exist.
