Struct Parameters 

pub struct Parameters { /* private fields */ }

Whereas Python offers variable arguments for its functions, Rust does not. The only way I’ve found to use variable arguments with function pointers is pass parameters stored in a single HashMap.

This type use a HashMap to store both usize parameters and string ones.

Implementations

impl Parameters

pub fn new() -> Self

Create a new Parameters type.

pub fn get_int(&self, key: &'static str) -> Result<usize>

Get value at given key assuming it is an usize value.

Error if given key does not exist or its value is not an usize.

Parameters:

• key: Key to search its value.

Returns

• Key’s value.

pub fn get_str(&self, key: &'static str) -> Result<String>

Get value at given key assuming it is an String value.

Error if given key does not exist or its value is not an String.

Parameters:

• key: Key to search its value.

Returns

• Key’s value.

pub fn insert_int(&mut self, key: &'static str, value: usize)

Insert an usize type at given key.

Parameters:

• key: Key to insert given value.

pub fn insert_str<T>(&mut self, key: &'static str, value: T)

where T: AsRef<str>,

Insert an String type at given key.

Parameters:

• key: Key to insert given value.

Trait Implementations

impl Clone for Parameters

fn clone(&self) -> Parameters

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
