Struct allsorts::binary::write::WriteCounter

pub struct WriteCounter { /* private fields */ }

A WriteContext implementation that just counts the bytes written.

Implementations

impl WriteCounter

pub fn new() -> Self

Create a new, empty WriteCounter

Trait Implementations

impl WriteContext for WriteCounter

fn write_bytes(&mut self, data: &[u8]) -> Result<(), WriteError>

Write a slice of bytes to a WriteContext.

fn write_zeros(&mut self, count: usize) -> Result<(), WriteError>

Write the specified number of zero bytes to the WriteContext.

fn bytes_written(&self) -> usize

The total number of bytes written so far.

fn write_placeholder<T, HostType>(
    &mut self,
    _placeholder: Placeholder<T, HostType>,
    val: HostType
) -> Result<T::Output, WriteError> where
    T: WriteBinary<HostType>, 

Consumes the placeholder and writes the supplied value into it

fn write_array<'a, T>(
    &mut self,
    array: &ReadArray<'a, T>
) -> Result<(), WriteError> where
    Self: Sized,
    T: ReadUnchecked<'a> + WriteBinary<<T as ReadUnchecked<'a>>::HostType>, 

Write a ReadArray instance to a WriteContext.

fn write_vec<'a, T>(
    &mut self,
    vec: Vec<<T as ReadUnchecked<'a>>::HostType>
) -> Result<(), WriteError> where
    Self: Sized,
    T: ReadUnchecked<'a> + WriteBinary<<T as ReadUnchecked<'a>>::HostType>, 

Write a Vec into a WriteContext.

fn placeholder<'a, T, HostType>(
    &mut self
) -> Result<Placeholder<T, HostType>, WriteError> where
    T: WriteBinary<HostType> + ReadUnchecked<'a>, 

Return a placeholder to T in the context for filling in later.

fn reserve<'a, T, HostType>(
    &mut self,
    count: usize
) -> Result<Placeholder<T, &'a HostType>, WriteError> where
    T: WriteBinary<&'a HostType>, 

Reserve space for count bytes in the context for filling in later.

fn placeholder_array<'a, T, HostType>(
    &mut self,
    count: usize
) -> Result<Vec<Placeholder<T, HostType>>, WriteError> where
    T: WriteBinary<HostType> + ReadUnchecked<'a>, 

Return a Vec of count placeholders of type T.
