Expand description

Type representing either a value, a table, an array of tables, or none.

Variants

None

Type representing none.

Value(Value)

Type representing value.

Table(Table)

Type representing table.

ArrayOfTables(ArrayOfTables)

Type representing array of tables.

Implementations

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

Downcasting

Text description of value type

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.

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.
