Recoverable errors are those that report to the user and retry the operation. Doing the insert of #2 but then updating the valueĮrrors can be grouped into two major categories: recoverable and unrecoverable errors.

scores.entry(String::from('Seattle Krakens')).or_insert(10).

scores.insert(String::from('Seattle Krakens'), 10).

When the owner goes out of scope, the value will be dropped.

Each value in Rust has a variable that’s called its owner.

If someone in your group comes late, they can ask where you’ve been seated to find you. When you enter, you state the number of people in your group, and the staff finds an empty table that fits everyone and leads you there. Pointers -> references to data (addresses) Rust is unique in the way that it allocates and frees memory, it uses an ownership model which is different C and different than JavaScript Some ways we talk about it is borrowing, slices, and memory. Ownership relates to several unique features to Rust. We can return values in a look with a breakįor element in a.iter() Chapter 4 - Ownership Ownership The types between the two cases must be same. Is a way for us to handle failed Result types from io.& reference and by default are also immutable.associated function ( ::) on the type and not an instance.Variables are default to immutable, so we add mut to change them.Interpretations of the lines and coupling it with things that may beĮxplicitly written to make sure I have a good understanding. This was a project chapter, so I am writing down a lot of my internal cargo build -release compiles with optimizations.May be useful to run more often than build if checking validity.cargo build - creates an executable from Cargo.toml.Will be found within the Cargo.toml files. In Rust, dependencies are referred to as crates. It also handles how toīuild our projects. We have a built-in dependency manager in Rust called Cargo. Super important to understanding each of their roles Unlike other programming languages such as JavaScript or Ruby, Rust splits apart It isn't just documentation butĪlso other pieces such as 'Rust by Example'. One can always get the documentationĭirectly with the terminal through rustup doc.

It is helpful for me to write out my raw thoughts Chapter 1ĭocumentation is local, offline avaibility. This is just a running list of notes along the way as I read the Rust Programming Notes - The Rust Programming Language Book
