Struct microkelvin::TokenBuffer

pub struct TokenBuffer { /* private fields */ }

Writebuffer guarded by a Token

Implementations

impl TokenBuffer

pub fn new(token: Token, buffer: &mut [u8]) -> Self

Construct a new TokenBuffer from a mutable slice of bytes and a token

pub fn consume(self) -> Token

Consume the buffer, returning the held token

pub fn written_bytes(&self) -> &[u8]

Return bytes that have been written into the tokenbuffer

pub unsafe fn unwritten_bytes(&mut self) -> &mut [u8]

Return bytes that have not yet been written

Safety

It is up to the caller to assure that Only one mutable reference may exist at a time

pub fn advance(&mut self) -> usize

Bump the buffer pointer forward, and reduce the internal count of written bytes.

Returns the amount of bytes written into the lbuffer

pub fn remap(&mut self, buffer: &mut [u8])

Remap TokenBuffer to the provided bytesg

Trait Implementations

impl AsMut<[u8]> for TokenBuffer

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl Fallible for TokenBuffer

type Error = BufferOverflow

The error produced by any failing methods.

impl Serializer for TokenBuffer

fn pos(&self) -> usize

Returns the current position of the serializer.

fn write(&mut self, bytes: &[u8]) -> Result<(), Self::Error>

Attempts to write the given bytes to the serializer.

fn pad(&mut self, padding: usize) -> Result<(), Self::Error>

Advances the given number of bytes as padding.

fn align(&mut self, align: usize) -> Result<usize, Self::Error>

Aligns the position of the serializer to the given alignment.

fn align_for<T>(&mut self) -> Result<usize, Self::Error>

Aligns the position of the serializer to be suitable to write the given type.

unsafe fn resolve_aligned<T>(
    &mut self,
    value: &T,
    resolver: <T as Archive>::Resolver
) -> Result<usize, Self::Error> where
    T: Archive + ?Sized, 

Resolves the given value with its resolver and writes the archived type.

fn serialize_value<T>(&mut self, value: &T) -> Result<usize, Self::Error> where
    T: Serialize<Self>, 

Archives the given object and returns the position it was archived at.

unsafe fn resolve_unsized_aligned<T>(
    &mut self,
    value: &T,
    to: usize,
    metadata_resolver: <T as ArchiveUnsized>::MetadataResolver
) -> Result<usize, Self::Error> where
    T: ArchiveUnsized + ?Sized, 

Resolves the given reference with its resolver and writes the archived reference.

fn serialize_unsized_value<T>(
    &mut self,
    value: &T
) -> Result<usize, Self::Error> where
    T: SerializeUnsized<Self> + ?Sized, 

Archives a reference to the given object and returns the position it was archived at.
