Struct prog_rs::file_progress::FileProgress

pub struct FileProgress { /* private fields */ }

A wrapper read only stream arround a file.

Example

use prog_rs::prelude::*;

let f = File::open("../../data/addresses/bano.csv")
    .unwrap()
    .progress()
    .with_prefix(" Read file ...")
    .with_bar_position(BarPosition::Right);
let f = BufReader::new(f);
println!("This file has {} lines", f.lines().count());

Trait Implementations

impl Debug for FileProgress

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

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

fn is_read_vectored(&self) -> bool

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

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> 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.

fn read_buf(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>

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

Read the exact number of bytes required to fill buf.

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

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

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

Creates an adapter which will chain this stream with another.

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

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

impl Seek for FileProgress

fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seek to an offset, in bytes, in a stream.

fn rewind(&mut self) -> Result<(), Error>

Rewind to the beginning of a stream.

fn stream_len(&mut self) -> Result<u64, Error>

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

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

Returns the current seek position from the start of the stream.

impl WithStepProgress for FileProgress

fn get_step_progress(&mut self) -> &mut StepProgress

fn with_humanize(self, humanize: bool) -> Self

Change wether units are converted to human-readable units.

fn with_unit<S: Into<String>>(self, unit: S) -> Self

Change displayed unit.

fn with_max_step(self, max_step: usize) -> Self

Update expected max step.

fn set_max_step(&mut self, max_step: usize)

Update expected max step.

fn max_step(&mut self) -> Option<usize>

Get expected max step.

fn cur_step(&mut self) -> usize

Get current step.
