Enum UIntByteRepr 

pub enum UIntByteRepr {
    ZeroOctet([u8; 1]),
    SingleOctet([u8; 2]),
    FourOctets([u8; 5]),
}

Represents the different byte encodings of a 32-bit unsigned signed.

This enum provides three variants based on the size of the signed’s encoding:

• ZeroOctet: Represents an signed value of 0, encoded as a single byte [0x43].
• SingleOctet: Represents integers that can fit into a single byte, encoded as two bytes [0x52, x].
• FourOctets: Represents integers requiring a full 32-bit representation, encoded as five bytes [0x70, x1, x2, x3, x4].

These formats are designed to handle encoded AMQP integers.

Variants

ZeroOctet([u8; 1])

Represents the zero-byte encoding of a 32-bit unsigned signed.

This variant is used when the signed value is 0. It is represented as a single byte [0x43].

Example

use flederfuchs_amqp::UIntByteRepr;

let encoding = UIntByteRepr::ZeroOctet([0x43]);
assert_eq!(encoding, UIntByteRepr::ZeroOctet([0x43]));

SingleOctet([u8; 2])

Represents the single-octet encoding of a 32-bit unsigned signed.

This variant is used when the signed value fits within a single byte. It is represented as two bytes [0x52, x], where x is the signed value.

Example

use flederfuchs_amqp::UIntByteRepr;

let encoding = UIntByteRepr::SingleOctet([0x52, 0x7F]);
assert_eq!(encoding, UIntByteRepr::SingleOctet([0x52, 0x7F]));

FourOctets([u8; 5])

Represents the four-octet encoding of a 32-bit unsigned signed.

This variant is used when the signed value requires the full 32-bit representation. It is represented as five bytes [0x70, x1, x2, x3, x4], where x1..x4 are the big-endian bytes of the signed value.

Example

use flederfuchs_amqp::UIntByteRepr;

let encoding = UIntByteRepr::FourOctets([0x70, 0x01, 0x02, 0x03, 0x04]);
assert_eq!(encoding, UIntByteRepr::FourOctets([0x70, 0x01, 0x02, 0x03, 0x04]));
