Implementations

impl Item

pub fn or_insert(&mut self, item: Item) -> &mut Item

Sets self to the given item iff self is none and returns a mutable reference to self.

impl Item

Downcasting

pub fn type_name(&self) -> &'static str

Text description of value type

pub fn get<I: Index>(&self, index: I) -> Option<&Item>

Index into a TOML array or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of an array.

Returns None if:

• The type of self does not match the type of the index, for example if the index is a string and self is an array or a number.
• The given key does not exist in the map or the given index is not within the bounds of the array.

pub fn get_mut<I: Index>(&mut self, index: I) -> Option<&mut Item>

Mutably index into a TOML array or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of an array.

Returns None if:

• The type of self does not match the type of the index, for example if the index is a string and self is an array or a number.
• The given key does not exist in the map or the given index is not within the bounds of the array.
