Instance Method

reserveCapacity(_:)

Reserves enough space in the view’s underlying storage to store the specified number of ASCII characters.

Declaration

mutating func reserveCapacity(_ n: Int)

Parameters

n

The minimum number of ASCII character’s worth of storage to allocate.

Discussion

Because a Unicode scalar value can require more than a single ASCII character’s worth of storage, additional allocation may be necessary when adding to a Unicode scalar view after a call to reserveCapacity(_:).

Complexity: O(n), where n is the capacity being reserved.
