Struct CodecFileReader 

pub struct CodecFileReader<R: Read + Seek> { /* private fields */ }

Streaming reader for a Level-2 TQCV corpus file.

Reads records sequentially without memory-mapping the file.

Implementations

impl<R: Read + Seek> CodecFileReader<R>

pub fn new(inner: R) -> Result<Self, IoError>

Open a TQCV corpus file from a seekable reader.

Reads and validates the Level-2 header, then positions the reader at the start of the body.

Errors

Returns IoError if the header is malformed, the magic is wrong, or the underlying I/O fails.

pub const fn header(&self) -> &CorpusFileHeader

Return a reference to the decoded Level-2 header.

pub fn next_vector(&mut self) -> Result<Option<CompressedVector>, IoError>

Read the next CompressedVector from the file.

Returns Ok(None) when all vector_count records have been read.

Errors

Returns IoError if the record is malformed or I/O fails.

pub const fn records_read(&self) -> u64

Number of records read so far.
