bin_io
is a crate inspired greatly by nom
and other parser combinator libraries. But bin_io
differs from those crates since it aims at providing both reading and writing facilities at the same time, with fewer code.
Add bin_io = "0.2"
to your Cargo.toml
In 0.2 bin_io
had a massive change, it now uses references while writing, and no longer needs an owned copy. This meant that some things needed to change from the last version, but everything should still work fine (with minor code changes, seq!
in particular), so check out the documentation!
use std::io::Cursor;
use bin_io::{ boilerplate, seq, read, write };
use bin_io::numbers::{ be_u8, be_u16 };
#[derive(Debug, PartialEq, Eq)]
struct Thing {
a: u8,
b: u16
}
boilerplate!(
fn thing_parser() -> Thing {
seq!(
Thing { a, b },
a: be_u8() =>
b: be_u16() =>
)
}
);
let mut vec = Vec::new();
let mut cursor = Cursor::new(vec);
let my_thing = Thing {
a: 0x10, b: 0x20
};
write(&mut cursor, &my_thing, thing_parser())
.unwrap();
cursor.set_position(0);
let other_thing = read(&mut cursor, thing_parser())
.unwrap();
assert_eq!(other_thing, my_thing);
