Trait indexed_file::IndexableFile

pub trait IndexableFile: Indexable {
    fn read_current_line(&mut self, buf: &mut Vec<u8>) -> Result<usize>;
    fn seek_line(&mut self, line: usize) -> Result<()>;
    fn write_to<W: Write + Unpin + Send>(
        &mut self, 
        writer: &mut W
    ) -> Result<usize>;

    fn get_offset(&self, line: usize) -> Result<u64> { ... }
}

Required methods

fn read_current_line(&mut self, buf: &mut Vec<u8>) -> Result<usize>

Should read from the current position until the end of the line, omitting the \n

fn seek_line(&mut self, line: usize) -> Result<()>

Should seek the file to the given line line

fn write_to<W: Write + Unpin + Send>(&mut self, writer: &mut W) -> Result<usize>

Write the index, followed by the files contents into writer. A file generated using this function will always be parsable by File::open.

Provided methods

fn get_offset(&self, line: usize) -> Result<u64>

Should return the offset to seek to given the line-index
