Trait DecodeWithLength 

pub trait DecodeWithLength: Sized {
    // Required method
    fn decode(src: &[u8], length: usize) -> Result<(Self, usize), DecodeError>;
}

Trait for decoding SMPP values from a slice with a specified length.

Implementation

#[derive(Debug, PartialEq, Eq)]
struct Foo {
    a: u8,
    b: u16,
    c: AnyOctetString,
}

impl DecodeWithLength for Foo {
    fn decode(src: &[u8], length: usize) -> Result<(Self, usize), DecodeError> {
        let index = 0;

        let (a, size) = Decode::decode(&src[index..])?;
        let index = index + size;

        let (b, size) = Decode::decode(&src[index..])?;
        let index = index + size;

        let (c, size) = AnyOctetString::decode(&src[index..], length - index)?;
        let index = index + size;

        Ok((Foo { a, b, c }, index))
    }
}

// Received over the wire
let length = 8;

let buf = &[0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09];

let expected = Foo {
    a: 0x01,
    b: 0x0203,
    c: AnyOctetString::new([0x04, 0x05, 0x06, 0x07, 0x08]),
};

let (foo, size) = Foo::decode(buf, length).unwrap();

assert_eq!(size, 8);
assert_eq!(foo, expected);
assert_eq!(&buf[size..], &[0x09]);

Required Methods

fn decode(src: &[u8], length: usize) -> Result<(Self, usize), DecodeError>

Decode a value from a slice, with a specified length

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.
