# Rust paths, use, and modules in files

**Answer:** Absolute and relative paths chain identifiers with `::`. Bringing a path into scope with `use` behaves like a filesystem symbolic link.

`mod` is not a textual include; it points Rust at the module's code in another file.

`use` can bind a full path to a shorter name for easier access.

## Claims

- id: C1
  claim: Paths are followed by identifiers separated by double colons.
  source: S1
  evidence: "Both absolute and relative paths are followed by one or more identifiers separated by double"
- id: C2
  claim: Adding use and a path is similar to creating a symbolic link.
  source: S2
  evidence: "Adding use and a path in a scope is similar to creating a symbolic link"
- id: C3
  claim: pub use makes an item available for others to bring into scope.
  source: S2
  evidence: "we're bringing an item into scope but also making that item available for others to"
- id: C4
  claim: mod is not an include operation from other languages.
  source: S3
  evidence: "mod is not an \"include\" operation that you may have seen in other programming languages."

- id: C5
  claim: The use declaration binds a full path to a new name for easier access.
  source: S4
  evidence: "The use declaration can be used to bind a full path to a new name,"
