once you have specified the name of package you want to use you need to go the Cargo.toml and add the package to the dependencies section.

[dependencies]
rand = "0.1.2" //rand package for generating nums

number of bits the int has, consistent accross all platforms

except for usize size of platforms pointer type can represent every memory address in the process

Also used to index into array or vector

signed ints are the same

max isize is upper bound of object and array size.

this lets it be used to calc differences between pointers and be able to address every byte within a value like a struct

the default is i32 because its generally the fastest

just because rust supports all types doesn’t mean all types are supported on all architectures!
