pub fn as_item_mut(&mut self) -> &mut Item

Returns a mutable reference to the root item.

pub fn as_table(&self) -> &Table

Returns a reference to the root table.

pub fn as_table_mut(&mut self) -> &mut Table

Returns a mutable reference to the root table.

pub fn iter(&self) -> Iter<'_>

Methods from Deref<Target = Table>

pub fn get_values(&self) -> Vec<(Vec<&Key>, &Value)>

Get key/values for values that are visually children of this table

For example, this will return dotted keys

pub fn fmt(&mut self)

Auto formats the table.

pub fn sort_values(&mut self)

Sorts Key/Value Pairs of the table.

Doesn’t affect subtables or subarrays.

pub fn sort_values_by<F>(&mut self, compare: F) where
    F: FnMut(&Key, &Item, &Key, &Item) -> Ordering, 

Sort Key/Value Pairs of the table using the using the comparison function compare.

The comparison function receives two key and value pairs to compare (you can sort by keys or values or their combination as needed).

pub fn set_implicit(&mut self, implicit: bool)

If a table has no key/value pairs and implicit, it will not be displayed.

Examples

[target."x86_64/windows.json".dependencies]

In the document above, tables target and target."x86_64/windows.json" are implicit.

use toml_edit::Document;
let mut doc = "[a]\n[a.b]\n".parse::<Document>().expect("invalid toml");

doc["a"].as_table_mut().unwrap().set_implicit(true);
assert_eq!(doc.to_string(), "[a.b]\n");

pub fn is_implicit(&self) -> bool

If a table has no key/value pairs and implicit, it will not be displayed.

pub fn set_dotted(&mut self, yes: bool)

Change this table’s dotted status

pub fn is_dotted(&self) -> bool

Check if this is a wrapper for dotted keys, rather than a standard table

pub fn set_position(&mut self, doc_position: usize)

Sets the position of the Table within the Document.

pub fn position(&self) -> Option<usize>
