[−][src]Struct read_progress::ReaderWithSize
A wrapper for a Read
that monitors how many bytes have been read, and how many are to go
Methods
impl<R: Read> ReaderWithSize<R>
[src]
pub fn new(total_size: usize, inner: R) -> Self
[src]
Create a ReaderWithSize from inner
presuming the total number of bytes is total_size
.
pub fn total_read(&self) -> usize
[src]
The total number of bytes that have been read from this reader
pub fn assummed_total_size(&self) -> usize
[src]
The assumed total number of bytes in this reader, created when this object was created.
pub fn fraction(&self) -> f64
[src]
How far along this reader have we read? What fraction have we read? May be >1.0 if the initial provided assumed total size was wrong.
pub fn into_inner(self) -> R
[src]
Consumer this, and return the inner Read
.
pub fn inner(&self) -> &R
[src]
A reference to the inner Read
.
impl ReaderWithSize<File>
[src]
pub fn from_path(path: impl Into<PathBuf>) -> Result<Self, Error>
[src]
Given a path, create a ReaderWithSize
based on that file size
