Implementations§

Source§

impl<'a> Entry<'a>

Source

pub fn key(&self) -> &str

Returns the entry key

§Examples
use toml_edit::Table;

let mut map = Table::new();

assert_eq!("hello", map.entry("hello").key());
Source

pub fn or_insert(self, default: Item) -> &'a mut Item

Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.

Source

pub fn or_insert_with<F: FnOnce() -> Item>(self, default: F) -> &'a mut Item

Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.
