Struct google_cloudprofiler2::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.

Methods

impl<'a> MultiPartReader<'a>

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

Reserve memory for exactly the given amount of parts

Important traits for MultiPartReader<'a>

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

pub fn add_part(     &mut self,     reader: &'a mut Read,     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>

Important traits for MultiPartReader<'a>

impl<'a> Read 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.

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.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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

Creates a "by reference" adaptor for this instance of Read.

Important traits for Bytes<R>

impl<R> Iterator for Bytes<R> where
    R: Read,  type Item = Result<u8, Error>;

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

Important traits for Chars<R>

impl<R> Iterator for Chars<R> where
    R: Read,  type Item = Result<char, CharsError>;

fn chars(self) -> Chars<Self>

Deprecated since 1.27.0

: Use str::from_utf8 instead: https://doc.rust-lang.org/nightly/std/str/struct.Utf8Error.html#examples

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

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an [Iterator] over [char]s.

Important traits for Chain<T, U>

impl<T, U> Read for Chain<T, U> where
    T: Read,
    U: Read, 

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

Creates an adaptor which will chain this stream with another.

Important traits for Take<T>

impl<T> Read for Take<T> where
    T: Read, 

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

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