Trait Implementations

impl<ErrType, R: CustomRead<ErrType>, BufferType: SliceWrapperMut<u8>, AllocU8: Allocator<u8>, AllocU32: Allocator<u32>, AllocHC: Allocator<HuffmanCode>> CustomRead<ErrType> for DecompressorCustomIo<ErrType, R, BufferType, AllocU8, AllocU32, AllocHC>

fn read(&mut self, buf: &mut [u8]) -> Result<usize, ErrType>

This variant of read will return Ok(number of bytes read) until the file Is completed at which point it will return Ok(0). However if there are additional unconsumed bytes in the buffer, it will return Err(InvalidData) at that point. Otherwise it will keep returning Ok(0).

Arguments

• buf - The buffer to read into

Errors

Returns Ok(0) if the file has been fully decompressed. If the file has been fully decompressed but there are additional non-brotli bytes in the buffer, then return an InvalidData error. Also upstream errors from the reader are returned.
