Struct SliceReader 

pub struct SliceReader<'a> { /* private fields */ }

A zero-copy, advancing reader for byte slices.

Implementations

impl<'a> SliceReader<'a>

pub fn new(slice: &'a [u8]) -> Self

pub fn read_bytes(&mut self, len: usize) -> DcbResult<&'a [u8]>

Safely takes len bytes from the front and advances the internal slice.

pub fn read_u8(&mut self) -> DcbResult<u8>

pub fn read_u16(&mut self) -> DcbResult<u16>

pub fn read_u32(&mut self) -> DcbResult<u32>

pub fn read_u64(&mut self) -> DcbResult<u64>

pub fn read_uuid(&mut self) -> DcbResult<Uuid>

pub fn read_page_id(&mut self) -> DcbResult<PageID>

pub fn read_position(&mut self) -> DcbResult<Position>

pub fn read_tsn(&mut self) -> DcbResult<Tsn>

pub fn read_str(&mut self, len: usize) -> DcbResult<&'a str>

Safely reads len bytes and validates them as a zero-copy UTF-8 string reference.

pub fn read_string(&mut self, len: usize) -> DcbResult<String>

Safely reads len bytes and allocates them into an owned String.

pub fn read_tag_hash(&mut self) -> DcbResult<[u8; 16]>

Reads a dynamically sized tag hash from disk and zero-pads it to the in-memory size.

pub fn remaining(&self) -> usize

Returns the number of unread bytes remaining.
