Struct trust_dns::serialize::binary::BinDecoder
[−]
[src]
pub struct BinDecoder<'a> { /* fields omitted */ }
This is non-destructive to the inner buffer, b/c for pointer types we need to perform a reverse seek to lookup names
A note on serialization, there was a thought to have this implement the rustc-serialization, but given that this is such a small subset of all the serialization which that performs this is a simpler implementation without the cruft, at least for serializing to/from the binary DNS protocols. rustc-serialization will be used for other coms, e.g. json over http
Methods
impl<'a> BinDecoder<'a>
[src]
fn new(buffer: &'a [u8]) -> Self
fn pop(&mut self) -> DecodeResult<u8>
fn len(&self) -> usize
fn peek(&self) -> Option<u8>
fn index(&self) -> usize
fn clone(&self, index_at: u16) -> BinDecoder
This is a pretty efficient clone, as the buffer is never cloned, and only the index is set to the value passed in
fn read_character_data(&mut self) -> DecodeResult<String>
the vector should be reversed before calling.
fn read_vec(&mut self, len: usize) -> DecodeResult<Vec<u8>>
fn read_u8(&mut self) -> DecodeResult<u8>
fn read_u16(&mut self) -> DecodeResult<u16>
parses the next 2 bytes into u16. This performs a byte-by-byte manipulation, there which means endianness is implicitly handled (i.e. no network to little endian (intel), issues)
the vector should be reversed before calling.
fn read_i32(&mut self) -> DecodeResult<i32>
parses the next four bytes into i32. This performs a byte-by-byte manipulation, there which means endianness is implicitly handled (i.e. no network to little endian (intel), issues)
the vector should be reversed before calling.
fn read_u32(&mut self) -> DecodeResult<u32>
parses the next four bytes into u32. This performs a byte-by-byte manipulation, there which means endianness is implicitly handled (i.e. no network to little endian (intel), issues)
the vector should be reversed before calling.
