A trait implemented by section readers.
Required Associated Types§
Required Methods§
sourcefn read(&mut self) -> Result<Self::Item, BinaryReaderError>
fn read(&mut self) -> Result<Self::Item, BinaryReaderError>
Reads an item from the section.
sourcefn original_position(&self) -> usize
fn original_position(&self) -> usize
Gets the original position of the reader.
Provided Methods§
sourcefn ensure_end(&self) -> Result<(), BinaryReaderError>
fn ensure_end(&self) -> Result<(), BinaryReaderError>
Ensures the reader is at the end of the section.
This methods returns an error if there is more data in the section than what is described by the section’s header.
