Trait print_bytes::ToBytes

source · [−]
pub trait ToBytes {
    fn to_bytes(&self) -> ByteStr<'_>;
}
Expand description

Represents a type similarly to Display.

Implement this trait to allow printing a type that cannot guarantee UTF-8 output. It is used to bound values accepted by functions in this crate.

Examples

use print_bytes::println_lossy;
use print_bytes::ByteStr;
use print_bytes::ToBytes;
#[cfg(windows)]
use print_bytes::WideStr;

struct ByteSlice<'a>(&'a [u8]);

impl ToBytes for ByteSlice<'_> {
    fn to_bytes(&self) -> ByteStr<'_> {
        self.0.to_bytes()
    }

    #[cfg(windows)]
    fn to_wide(&self) -> Option<WideStr> {
        self.0.to_wide()
    }
}

println_lossy(&ByteSlice(b"Hello, world!"));

Required Methods

Returns a byte string that will be used to represent the instance.
