在5月8日的第三阶段培训开始前完成所有的第二阶段lab
完成rustlings。学习不规律之后速度显著变慢……还是应该规律地周期地学习
完成rustlings，推进rcore至上一次做到的进度。
第19天完成《Programming Rust》所有章节。超前计划4天完成。大概投入时间在45小时左右。

《Programming Rust》ch06
6 Expressions An Expression Language Precedence and Associativity Blocks and Semicolons Declarations if and match if let Loops Control Flow in Loops return Expressions Why Rust Has loop Function and Method Calls Fields and Elements Reference Operators Arithmetic, Bitwise, Comparison, and Logical Operators
未学
复习Rust，完成《Programming Rust》ch03、ch04、ch05
结合生命周期确保引用有效 - Rust 程序设计语言，这次真的理解了生命周期参数还有reference到底是怎么一回事。
3 Fundamental Types Arrays, Vectors, and Slices Arrays Vectors Slices String Types String Literals Byte Strings Strings in Memory String Using Strings Other String-Like Types Type Aliases Beyond the Basics
4 Ownership and Moves Ownership Moves More Operations That Move Moves and Control Flow Moves and Indexed Content Copy Types: The Exception to Moves Rc and Arc: Shared Ownership
5 References References to Values Working with References Rust References Versus C++ References Assigning References References to References Comparing References References Are Never Null Borrowing References to Arbitrary Expressions References to Slices and Trait Objects Reference Safety Borrowing a Local Variable Receiving References as Function Arguments Passing References to Functions Returning References Structs Containing References Distinct Lifetime Parameters Omitting Lifetime Parameters Sharing Versus Mutation Taking Arms Against a Sea of Objects
复习Rust，完成《Programming Rust》ch3，看到指针
3 Fundamental Types Fixed-Width Numeric Types Integer Types Checked, Wrapping, Saturating, and Overflowing Arithmetic Floating-Point Types The bool Type Characters Tuples Pointer Types References Boxes Raw Pointers
复习Rust，完成《Programming Rust》ch2，开始看ch3

2 A Tour of Rust rustup and Cargo Rust Functions Writing and Running Unit Tests Handling Command-Line Arguments Serving Pages to the Web
上一次做到stripe调度，后面的就没做了，这次提升了debug能力之后，回来重做。
总结上一次的教训，暴发式的学习不可取，应该日积月累，每天投入固定的时间学习。
先把rust的基础打得再扎实一点。每天2小时。
