STRING_LITERAL :" (~["\IsolatedCR]|QUOTE_ESCAPE|ASCII_ESCAPE|UNICODE_ESCAPE|STRING_CONTINUE)*"STRING_CONTINUE :\ followed by \n 以一对双引号包含的多个合法的Unicode character(Unicode字符?),可以包含双引号自身,但是此时要以斜杠转义,并允许使用"\"换行,此时下一行行首的所有空白字符会被自动去除,如...
fn takes_str(s: &str) { } let s = String::from("Hello"); takes_str(&s); 这将根据String创建一个&str并将其传递。这种转换开销很低,因此通常函数会使用&strs作为参数,除非出于某些特定原因需要使用String。在某些情况下,Rust没有足够的信息来进行这种转换,称为Deref强制转换。 在以下示例中,字符串...

asyncfnexample(min_len:usize) -> String Since the complete function body is now implemented by the state machine, the only thing that the function needs to do is to initialize the state machine and return it. The generated code for this could look like this: ...
Iterate in sequence over the elements of the list items1 then items2. For each iteration print the element.
Reversing Strings: Use .chars().rev() to reverse a string while preserving UTF-8 correctness. Slicing Strings: Safely slice strings by specifying valid byte indices, ensuring you don't split a character in half. These operations are essential building blocks when working with strings in Rust. ...
