bin_io
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.
Usage
Add bin_io = "0.2"
to your Cargo.toml
Big change in 0.2
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!
Example
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);
