Struct bytecodec::fixnum::U40beEncoder [−][src]
pub struct U40beEncoder(_);
Encoder which encodes unsigned 40-bit integers by big-endian byte order.
Although the type of items is u64
, the most significant 24-bits must be 0
.
Examples
use bytecodec::EncodeExt; use bytecodec::fixnum::U40beEncoder; use bytecodec::io::IoEncodeExt; let mut output = Vec::new(); let mut encoder = U40beEncoder::with_item(0x0000_0001_0203_0405).unwrap(); encoder.encode_all(&mut output).unwrap(); assert_eq!(output, [0x01, 0x02, 0x03, 0x04, 0x05]);
