Struct finalfrontier_utils::FileProgress

pub struct FileProgress { /* fields omitted */ }

Methods

impl FileProgress

A progress bar that implements the Read trait.

This wrapper of indicatif's ProgressBar updates progress based on the current offset within the file.

pub fn new(file: File) -> Result<Self>

Trait Implementations

impl Drop for FileProgress

fn drop(&mut self)

Executes the destructor for this type.

impl Read for FileProgress

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.

default fn read_vectored(
    &mut self,
    bufs: &mut [IoVecMut]
) -> Result<usize, Error>

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

Like read, except that it reads into a slice of buffers.

unsafe default fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

default 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.

default fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

default fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

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

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

default fn bytes(self) -> Bytes<Self>

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

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

Creates an adaptor which will chain this stream with another.

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

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