Struct ncmdump::QmcDump

pub struct QmcDump<S>where
    S: Read,{ /* private fields */ }

The qmc file dump wrapper.

Implementations

impl<S> QmcDump<S>where S: Read,

pub fn from_reader(reader: S) -> Result<Self, Errors>

Create QmcDump from reader.

Example

let file = File::open("tests/test.qmcflac").expect("Can't open file");
let _ = QmcDump::from_reader(file).unwrap();

examples/qcmdump.rs (line 14)

fn main() -> Result<()> {
    let file = File::open("tests/test.qmcflac")?;
    let mut qmc = QmcDump::from_reader(file)?;
    let data = qmc.get_data()?;

    let mut target = File::options()
        .create(true)
        .write(true)
        .open("tests/test.flac")?;
    target.write_all(&data)?;
    Ok(())
}

pub fn get_data(&mut self) -> Result<Vec<u8>>

Get the music data from qmcdump.

Example:

use std::fs::File;
use std::io::Write;
use std::path::Path;

use anyhow::Result;
use ncmdump::QmcDump;

fn main() -> Result<()> {
    let file = File::open("tests/test.qmcflac")?;
    let mut qmc = QmcDump::from_reader(file)?;
    let music = qmc.get_data()?;

    let mut target = File::options()
        .create(true)
        .write(true)
        .open("tests/test.flac")?;
    target.write_all(&music)?;
    Ok(())
}

Trait Implementations

impl<R> Read for QmcDump<R>where R: Read,

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: BorrowedCursor<'_>) -> 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, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Read the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

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

fn bytes(self) -> Bytes<Self>where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

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

Creates an adapter which will chain this stream with another.

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

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

impl<R> Seek for QmcDump<R>where R: Read + Seek,

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.
