b formateo.
los Binary el rasgo debe formatear su salida como un número en binario.
Para enteros primitivos con signo (i8 para i128, y isize), los valores negativos se formatean como la representación del complemento a dos.
La bandera alternativa, #, agrega un 0b delante de la salida.
Para obtener más información sobre formateadores, consulte la documentación a nivel de módulo.
Ejemplos de
Uso básico con i32:
let x =42;// 42 is '101010' in binaryassert_eq!(format!(":b", x),"101010");assert_eq!(format!(":#b", x),"0b101010");assert_eq!(format!(":b",-16),"11111111111111111111111111110000");
Implementar Binary en un tipo:
usestd::fmt;structLength(i32);implfmt::BinaryforLengthfnfmt(&self, f:&mutfmt::Formatter<'_>)->fmt::Resultlet val =self.0;fmt::Binary::fmt(&val, f)// delegate to i32's implementationlet l =Length(107);assert_eq!(format!("l as binary is: :b", l),"l as binary is: 1101011");assert_eq!(format!("l as binary is: :#032b", l),"l as binary is: 0b000000000000000000000001101011");
