Struct taskcluster_download::CursorWriterFactory

source · [−]

pub struct CursorWriterFactory<T>(_);

Expand description

A CusorWriterFactory creates AsyncWrite objects from a std::io::Cursor, allowing downloads to in-memory buffers. It is specialized for Vec (which grows indefinitely) and &mut [u8] (which has a fixed maximum size)

Implementations

source

impl CursorWriterFactory<Vec<u8>>

source

pub fn new() -> Self

source

pub fn into_inner(self) -> Vec<u8>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

Consume the factory, returning the vector into which the data was read

source

impl<'a> CursorWriterFactory<&'a mut [u8 ]>

source

pub fn for_buf(inner: &'a mut [u8 ]) -> Self

source

pub fn size(self) -> usize

Return the size of the data written to the buffer. This value should be used to slice the resulting data from the buffer.
