Struct google_safebrowsing4::client::MultiPartReader

pub struct MultiPartReader<'a> { /* fields omitted */ }

Provides a Read interface that converts multiple parts into the protocol identified by RFC2387. Note: This implementation is just as rich as it needs to be to perform uploads to google APIs, and might not be a fully-featured implementation.

Implementations

impl<'a> MultiPartReader<'a>

pub fn reserve_exact(&mut self, cap: usize)

Reserve memory for exactly the given amount of parts

pub fn add_part(
    &mut self,
    reader: &'a mut (dyn Read + Send),
    size: u64,
    mime_type: Mime
) -> &mut MultiPartReader<'a>

Add a new part to the queue of parts to be read on the first read call.

Arguments

headers - identifying the body of the part. It’s similar to the header in an ordinary single-part call, and should thus contain the same information. reader - a reader providing the part’s body size - the amount of bytes provided by the reader. It will be put onto the header as content-size. mime - It will be put onto the content type

pub fn mime_type(&self) -> Mime

Returns the mime-type representing our multi-part message. Use it with the ContentType header.

Trait Implementations

impl<'a> Default for MultiPartReader<'a>

fn default() -> MultiPartReader<'a>

Returns the “default value” for a type.

impl<'a> Read for MultiPartReader<'a>

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.

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

Creates a “by reference” adapter 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.
