[−][src]Crate byte_struct
Byte Struct
Pack and unpack structure as raw bytes with packed or bit field layout.
Example
use byte_struct::*; bitfields!( #[derive(PartialEq, Debug)] GIFColorTableInfo: u8 { global_color_table_flag: 1, color_resolution: 3, sort_flag: 1, global_color_table_size: 3, } ); #[derive(ByteStruct, PartialEq, Debug)] #[byte_struct_le] struct GIFLogicalScreenDescriptor { width: u16, height: u16, color_table_info: GIFColorTableInfo, background_color_index: u8, pixel_aspect_ratio: u8, } fn example() { assert_eq!(GIFLogicalScreenDescriptor::BYTE_LEN, 7); let raw_descriptor = [0x03, 0x00, 0x05, 0x00, 0xF7, 0x00, 0x00]; let descriptor = GIFLogicalScreenDescriptor::read_bytes(&raw_descriptor[..]); assert_eq!(descriptor, GIFLogicalScreenDescriptor{ width: 3, height: 5, color_table_info: GIFColorTableInfo { global_color_table_flag: 1, color_resolution: 3, sort_flag: 1, global_color_table_size: 7, }, background_color_index: 0, pixel_aspect_ratio: 0, }); let mut raw_another = [0; GIFLogicalScreenDescriptor::BYTE_LEN]; descriptor.write_bytes(&mut raw_another[..]); assert_eq!(raw_descriptor, raw_another); }
