Struct LocalFileAccessor 

pub struct LocalFileAccessor { /* private fields */ }

Local file accessor using memory mapping

Implementations

impl LocalFileAccessor

pub async fn new(file_path: PathBuf) -> Result<Self>

Create a new local file accessor

pub fn path(&self) -> &PathBuf

Get file path

pub fn as_slice(&self) -> &[u8]

Get direct reference to mapped memory (zero-copy)
