Trait Alias instrs_core::Size
source · Expand description
Represents a type that can be used to encode the size of a variable-length struct like
Vec and String. For example, a u8
will be cheap and efficient, but
every vec in the bytecode can only be a maximum of 256 items long.
assert_eq!(
<Vec::<u8>>::from_bytes::<u8>(&mut [3,1,2,3].as_slice()),
Ok(vec![1,2,3])
);
assert_eq!(
<Vec::<u8>>::from_bytes::<u16>(&mut [3,0, 1,2,3].as_slice()),
Ok(vec![1,2,3])
);
Note: You should not use a usize
since this makes your bytecode platform-dependent.
