Struct d4_framefile::Stream

pub struct Stream<T> { /* private fields */ }

Implementations

impl<T> Stream<T>

pub fn set_frame_size(&mut self, size: usize)

pub fn double_frame_size(&mut self, limit: usize)

pub fn get_frame_capacity(&self) -> usize

impl<T: Read + Write + Seek> Stream<T>

pub fn flush(&mut self) -> Result<()>

pub fn write(&mut self, buffer: &[u8]) -> Result<usize>

pub fn disable_pre_alloc(&mut self)

pub fn write_frame(&mut self, buffer: &[u8]) -> Result<()>

pub fn write_with_alloc_callback<R: FnMut(&mut Self)>(
    &mut self,
    buffer: &[u8],
    callback: R
) -> Result<usize>

Append data to the given stream. Similar to write, but this allows to inject a callback function, which you can modify the configuration of the stream before the stream actually synced to the file.

impl<T: Read + Seek> Stream<T>

pub fn load_next_frame(&mut self) -> Result<()>

pub fn read_current_frame(&self) -> Option<&[u8]>

pub fn copy_current_frame_data(&self, buf: &mut Vec<u8>)

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

impl<'a, T: Read + Write + Seek> Stream<T>

pub fn update_current_byte(&mut self, byte: u8) -> Result<usize>

Trait Implementations

impl<T: Read + Seek> AsRef<[u8]> for Stream<T>

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl<T> Drop for Stream<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Read + Seek> Read for Stream<T>

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (read_buf)

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adapter which will read at most limit bytes from it.

impl<T: Read + Write + Seek> Write for Stream<T>

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

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adapter for this instance of Write.
