Function nanogrep::run

pub fn run(config: Config) -> Result<(), Box<dyn Error>>

Runs the library logic. The functions expects a reference to a Config struct containing:

• file: The file in which the search will be conducted
• pattern: The pattern to search for in the contents of the file

If the execution runs without any problem, the function returns (). If not, a Box<std::error::Error> struct is returned.

Errors

The function returns errors on the following situations:

• file doesn't exist
• file could not be read (unauthorized read permission)
