Trait BinaryRead 

pub trait BinaryRead: Read {
    // Provided methods
    fn read_binary_boxed<T>(&mut self) -> Result<Box<T>> { ... }
    fn read_binary<T>(&mut self) -> Result<T> { ... }
}

The BinaryRead trait allows for reading data structures out of binary sources.

Examples

struct MyStruct {
    some: char,
    // fields
}

use binext::BinaryRead;
use std::{io, fs};

fn main() -> io::Result<()> {
    let mut file = fs::File::open("myfile.bin")?;

    // This returns an instance of the file that was in the file.
    // Please note that for this method to work properly, the data must be written beforehand
    // into the file.
    let instance = file.read_binary::<MyStruct>()?;

    Ok(())
}

Provided Methods

fn read_binary_boxed<T>(&mut self) -> Result<Box<T>>

Reads from a binary source and converts the bytes into the specified structure, returning a Boxed structure.

Examples

struct MyStruct {
    some: char,
    // fields
}

use binext::BinaryRead;
use std::{io, fs};

fn main() -> io::Result<()> {
    let mut file = fs::File::open("myfile.bin")?;

    // This returns an instance of the file that was in the file.
    // Please note that for this method to work properly, the data must be written beforehand
    // into the file.
    let instance = file.read_binary_boxed::<MyStruct>()?;

    Ok(())
}

fn read_binary<T>(&mut self) -> Result<T>

Reads from a binary source and converts the bytes into the specified structure.

Examples

struct MyStruct {
    some: char,
    // fields
}

use binext::BinaryRead;
use std::{io, fs};

fn main() -> io::Result<()> {
    let mut file = fs::File::open("myfile.bin")?;

    // This returns an instance of the file that was in the file.
    // Please note that for this method to work properly, the data must be written beforehand
    // into the file.
    let instance = file.read_binary::<MyStruct>()?;

    Ok(())
}

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
