Struct openssl::bio::MemBio

pub struct MemBio { /* fields omitted */ }

Methods

impl MemBio

pub fn new() -> Result<MemBio, SslError>

Creates a new owned memory based BIO

Important traits for MemBio

impl Write for MemBioimpl Read for MemBio

pub fn borrowed(bio: *mut BIO) -> MemBio

Returns a "borrow", i.e. it has no ownership

pub unsafe fn unwrap(self) -> *mut BIO

Consumes current bio and returns wrapped value Note that data ownership is lost and should be managed manually

pub unsafe fn get_handle(&self) -> *mut BIO

Temporarily gets wrapped value

pub fn set_eof(&self, eof: bool)

Sets the BIO's EOF state.

Trait Implementations

impl Drop for MemBio

fn drop(&mut self)

Executes the destructor for this type.

impl Write for MemBio

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.

impl Read for MemBio

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.

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

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, 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 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 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.
