grow method

void grow(
  1. num n
)

Grows the buffer's capacity, if necessary, to guarantee space for another n bytes. After .grow(n), at least n bytes can be written to the buffer without another allocation. If n is negative, .grow() will throw. If the buffer can't grow it will throw an error.

Based on Go Lang's Buffer.Grow.

Implementation

void grow(_i2.num n) {
  _i3.callMethod(
    this,
    'grow',
    [n],
  );
}
