payload of the Value::Array
variant’s value

Formatting
Set whether the array will use a trailing comma
Whether the array will use a trailing comma
Set whitespace after last element
Returns an iterator over all values.
Returns the length of the underlying Vec.
In some rare cases, placeholder elements will exist. For a more accurate count, call
a.iter().count()
Examples
let mut arr = toml_edit::Array::new();
arr.push(1);
arr.push("foo");
assert_eq!(arr.len(), 2);
Return true iff self.len() == 0
.
Examples
let mut arr = toml_edit::Array::new();
assert!(arr.is_empty());
arr.push(1);
arr.push("foo");
assert!(! arr.is_empty());
Clears the array, removing all values. Keeps the allocated memory for reuse.
Returns a reference to the value at the given index, or None
if the index is out of
bounds.
Returns a reference to the value at the given index, or None
if the index is out of
bounds.
Appends a new value to the end of the array, applying default formatting to it.
Examples
let mut arr = toml_edit::Array::new();
arr.push(1);
arr.push("foo");
Appends a new, already formatted value to the end of the array.
Examples
let formatted_value = "'literal'".parse::<toml_edit::Value>().unwrap();
let mut arr = toml_edit::Array::new();
arr.push_formatted(formatted_value);
Inserts an already formatted value at the given position within the array, shifting all values after it to the right.
Panics
Panics if index > len
.
Examples
let mut arr = toml_edit::Array::new();
arr.push(1);
arr.push("foo");
let formatted_value = "'start'".parse::<toml_edit::Value>().unwrap();
arr.insert_formatted(0, formatted_value);
Replaces the element at the given position within the array with an already formatted value.
Panics
Panics if index >= len
.
Examples
let mut arr = toml_edit::Array::new();
arr.push(1);
arr.push("foo");
let formatted_value = "'start'".parse::<toml_edit::Value>().unwrap();
arr.replace_formatted(0, formatted_value);
