Shrink

Releases unused capacity.

Module: Std

Signature

func Shrink(self);

Description

Reallocates the buffer down to exactly Length bytes, freeing any slack between the length and the capacity. Does nothing if the builder is already full or empty. Useful before holding a builder around for a long time, though most code converts to a String instead.

Example

import Std::StringBuilder;

var sb = StringBuilder::WithCapacity(1024);
sb.Append("short");
sb.Shrink();                 // capacity drops to 5
