as you would expect in C. However with the exception of arrays (which are densely packed and in-order), the layout of data is not specified by default. Given the two following struct definitions:
InvalidFlushedDelayedDiagnosticLevel是一个结构体,表示在刷新延迟错误或警告时出现无效的级别。 IndicateAnonymousLifetime是一个结构体,表示指示匿名生命周期的错误或警告。 这些结构体和枚举类型用于构建和表示不同类型的错误和警告信息,通过对它们的实例化和使用,可以方便地生成和处理对应的诊断信息。 LabelKind是一个枚...
An item is a component of a crate. Items are organized within a crate by a nested set of modules. Every crate has a single "outermost" anonymous module; all further items within the crate have paths within the module tree of the crate. There are several kinds of items: modules extern c...

SilentEmitter:该struct是一个静默的错误信息输出器。它忽略了所有的错误信息。 EmitterWriter:该struct是错误信息输出器的一个包装类,它负责将错误信息写入指定的输出流,例如标准输出流或文件。 FileWithAnnotatedLines:该struct表示一个带有注释行的文件。它包含了文件的路径和注释行的集合。

Tuples are like anonymous structs, and accessing an element in a tuple behaves like accessing a struct field. Structs can be partially borrowed (and also partially moved), so &mut out2.a.0.in_a borrows only the first field of the tuple. The same does not apply to indexing. The indexin...
