Struct valid_toml::ItemStr

pub struct ItemStr { /* fields omitted */ }

This item is used to read an string value from the TOML file

Methods

impl ItemStr

fn with_name<T: AsRef<str>>(name: T) -> ItemStr

Constructs a new instance of the ItemUsize object.

fn add_to(self, group: &mut TomlDef) -> StringValue

Adds the item to a group and returns an option that will receive the item's value when the file is loaded. Basically this allows a program to receive a value laoded from the file without getting the TomlData object that was created.

Examples

use valid_toml::{TomlDef, ItemStr, ItemUsize};

let file = r#"
    password = "secret"
    count   = 15
    "#;

let mut def = TomlDef::new();

let password = ItemStr::with_name("password").min(3).max(8).add_to(&mut def);
let count    = ItemUsize::with_name("count").optional().add_to(&mut def);

let file = def.parse_toml(file).unwrap();

assert_eq!(password.get(), "secret");
assert_eq!(count.get(), 15);

fn min(self, min: usize) -> Self

Defines the minimum length the string can be.

fn max(self, max: usize) -> Self

Defines the maximum length the string can be.

fn optional(self) -> Self

Marks the item as optional without providing a default value.

fn default<T: AsRef<str>>(self, default: T) -> Self

Defines the default value for the item. This method makes the item optional. The default value will only be used if the parent group exists.
