Struct memstream::MemStream

pub struct MemStream {
    // some fields omitted
}

MemStream is a reader + writer stream backed by an in-memory buffer

Methods

impl MemStream

fn new() -> MemStream

Creates a new MemStream which can be read and written to

fn eof(&self) -> bool

Tests whether this stream has read all bytes in its ring buffer If true, then this will no longer return bytes from read

fn as_slice<'a>(&'a self) -> &'a [u8]

Acquires an immutable reference to the underlying buffer of this MemStream

fn unwrap(self) -> Vec<u8>

Unwraps this MemStream, returning the underlying buffer

Trait Implementations

impl Read for MemStream

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_to_end(&mut self, buf: &mut Vec<u8>) -> 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, placing them into buf.

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

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 chars(self) -> Chars<Self>

Transforms this Read instance to an Iterator over chars.

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

Creates an adaptor which will chain this stream with another.

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

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

impl Write for MemStream

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

Write a buffer into this object, 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_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this write.

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" adaptor for this instance of Write.

Derived Implementations

impl PartialOrd for MemStream

fn partial_cmp(&self, __arg_0: &MemStream) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &MemStream) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &MemStream) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &MemStream) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &MemStream) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq for MemStream

fn eq(&self, __arg_0: &MemStream) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &MemStream) -> bool

This method tests for !=.
