File To Map struct

Implementations

impl<'a> FileToMap<'a>

pub fn new(file_name: &'a str) -> Self

Creates a new struct. The file won’t be parsed until calling the build function.

pub fn set_key_value_separator(self, sep: &'a str) -> Self

Changes the key-value pair separator. The default is =.

pub fn set_pair_separator(self, sep: &'a str) -> Self

Changes the pairs separator. The default is just a new line, but can be changed to any string.

pub fn build(self) -> Result<Self, Error>

This function parses the file and creates the map. Call this function after changing the separators (if necessary). Be aware - this function returns a result struct. it will return an error due to an IO file error or missing key-value separator.

pub fn get(&self, key: &str) -> Option<&String>

Get value by key, same as get() of HashMap struct.

Trait Implementations

impl<'a> Index<&str> for FileToMap<'a>

fn index(&self, key: &str) -> &String

Get value by key, using [“key”] (index operator).

Panic

The function will panic when the key isn’t in the map.

type Output = String

The returned type after indexing.
