Hello World!
Several terminologies of Rust:
Cargo: The construction tool of the rust language. It is very image-oriented. It refers to trucks.
Crate: equivalent to java jar package, so of c/c ++. Wicker boxes. Various wicker boxes are installed in the van.
Rustc: The rust compiler.

. ClassIn the study of objects, the main consideration is the properties and behavior of objects, and some different objects will present the same or similar properties and behaviors, such as cars, trucks, vans. Attributes and behaviors are usually grouped into one category or similar objects. A class can be viewed as an abstraction of an object, representing the common properties and behavior of such an object. The typical class is "human", which ind
is 4096 bytes.
Our hard disks are already above the TB level. How can this be converted?
1 TB = 1024 GB
1 GB = 1024 MB
1 MB = 1024KB
1KB = 1024 bytes)
1 Byte (Byte) = 8bit (BIT)
The new 5-byte text is 40 bytes if it is converted into a computer binary.
Our memory stick is actually a small lattice or contains many small locations to store data.
A small position is a single position.
We just entered 12345 and used 40 locations in the memory.

You can talk about staggered parallelism and imagine multiple trucks sharing the same lane. This is why interleaved concurrency is also defined as a kind of virtual parallelism.Concurrency means that different code can be executed at the same time, taking full advantage of the concurrency of the underlying hardware.

past. Suppose you have a library called "Fire Truck," which requires another suite called "Ladder" and already has a set of semantics for versioning. When a fire truck is created, the ladder version number is 3.1.0. Because fire trucks use some of the new features of version 3.1.0, you can safely specify that the version number dependent on the ladder is equal to 3.1.0 but less than 4.0.0. This way, when the ladder versions 3.1.1 and 3.2.0 are releas
