1. Integer Type In Rust, we use integer data types to store whole numbers. For example, let number: i32 = 200; Here, we have created the number variable of type i32 (integer) and stored the value 200. The integer type i32 has two parts to it: i - specifies signed integer type (...
Rust的变量类型__Data type Every value in Rust is of a certaindata type, which tells Rust what kind of data is being specified so it knows how to work with that data. We’ll look at two data type subsets:scalarandcompound.在Rust中每一个值都有确定的变量类型,以告知Rust使用的数据是哪一...

rust 基础 - datatype /// 数据类型/// 两类数据类型 :标量(scalar) 和 复合(compound)。/// 标量(scalar)类型代表一个单独的值。/// Rust 有四种基本的标量类型:整型、浮点型、布尔 类型和字符类型。/// i8 i16 i32 i64 i128 isize/// u8 u16 u32 u64 u128 usize/// isize usize 类型长度 ...
rust学习——泛型(generics Data Types) 我们可以使用泛型为诸如函数签名或结构之类的项创建定义,然后可以将其用于许多不同的具体数据类型。 首先让我们看一下如何使用泛型定义函数,结构,枚举和方法。 然后,我们将讨论泛型如何影响代码性能。 在函数定义中 举个例子,如果我们定义两个函数,分别是求最大值和最大字符串...
Float data type in Rust can be classified as f32 and f64. The f32 type is a single-precision float, and f64 has double precision. The default type is f64. Consider the following example to understand more about the float data type....
我们可以更深一步,当我们让Rust将一个类型产生的位模式当成另一种类型使用时,会发生什么?下面的listing提供了一个答案。 // Listing 5.2fnmain(){leta:f32=42.42;letfrankentype:u32=unsafe{std::mem::transmute(a)};// 将f32类型的42.42的位串按小数查看println!("{}",frankentype);// {:032b}代表...
