Struct google_ml1::MultiPartReader [−][src]
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>
[src]
impl<'a> MultiPartReader<'a>
pub fn reserve_exact(&mut self, cap: usize)
[src]
pub fn reserve_exact(&mut self, cap: usize)
Reserve memory for exactly the given amount of parts
ⓘImportant traits for MultiPartReader<'a>pub fn add_part(
&mut self,
reader: &'a mut Read,
size: u64,
mime_type: Mime
) -> &mut MultiPartReader<'a>
[src]
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
[src]
pub fn mime_type(&self) -> Mime
Returns the mime-type representing our multi-part message. Use it with the ContentType header.
