Struct bytecodec::fixnum::U24beDecoder
[−]
[src]
pub struct U24beDecoder(_);
Decoder which decodes unsigned 24-bit integers by big-endian byte order.
The type of decoded values is u32
, but the most significant 8-bits always be 0
.
Examples
use bytecodec::Decode; use bytecodec::fixnum::U24beDecoder; use bytecodec::io::IoDecodeExt; let mut decoder = U24beDecoder::new(); let item = decoder.decode_exact([0x01, 0x02, 0x03].as_ref()).unwrap(); assert_eq!(item, 0x0001_0203u32);
