Struct toml_edit::Table

pub struct Table { /* fields omitted */ }

Type representing a TOML non-inline table

Methods

impl Table

pub fn new() -> Self

Creates an empty table.

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

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 iter(&self) -> Iter

Returns an iterator over all key/value pairs, including empty.

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

Removes an item given the key.

pub fn sort_values(&mut self)

Sorts Key/Value Pairs of the table, doesn't affect subtables or subarrays.

pub fn len(&self) -> usize

Returns the number of non-empty items in the table.

pub fn values_len(&self) -> usize

Returns the number of key/value pairs in the table.

pub fn is_empty(&self) -> bool

Returns true iff the table is empty.

pub fn entry<'a>(&'a mut self, key: &str) -> &'a mut Item

Given the key, return a mutable reference to the value. If there is no entry associated with the given key in the table, a Item::None value will be inserted.

To insert to table, use entry to return a mutable reference and set it to the appropriate value.

pub fn get<'a>(&'a self, key: &str) -> Option<&'a Item>

Returns an optional reference to an item given the key.

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.

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");

Trait Implementations
