Type representing a TOML non-inline table

Implementations

impl Table

Constructors

See also FromIterator

pub fn new() -> Self

Creates an empty table.

pub fn into_inline_table(self) -> InlineTable

Convert to an inline array

impl Table

Formatting

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 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, position: usize)

Sets the position of the Table within the Document.

Setting the position of a table will only affect output when Document::to_string_in_original_order is used.

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

The position of the Table within the Document.

Returns None if the Table was created manually (i.e. not via parsing) in which case its position is set automatically.

Returns the surrounding whitespace

pub fn decor(&self) -> &Decor

Returns the decor associated with a given key of the table.

Returns true iff the table contains an item with the given key.

pub fn contains_table(&self, key: &str) -> bool

Returns true iff the table contains a table with the given key.

pub fn contains_value(&self, key: &str) -> bool

Returns true iff the table contains a value with the given key.

pub fn contains_array_of_tables(&self, key: &str) -> bool

Returns true iff the table contains an array of tables with the given key.

pub fn insert(&mut self, key: &str, item: Item) -> Option<Item>

Inserts a key-value pair into the map.

pub fn insert_formatted(&mut self, key: &Key, item: Item) -> Option<Item>

Inserts a key-value pair into the map.

pub fn remove(&mut self, key: &str) -> Option<Item>

Removes an item given the key.

pub fn remove_entry(&mut self, key: &str) -> Option<(Key, Item)>

Removes a key from the map, returning the stored key and value if the key was previously in the map.
