writeAll method

Future<void> writeAll(
  1. IoSlice src
)

Writes all bytes in src, looping over short writes.

Implementation

Future<void> writeAll(IoSlice src) async {
  var offset = 0;
  while (offset < src.length) {
    final n = await writeFrom(
      IoSlice(src.bytes, start: src.start + offset, end: src.end),
    );
    if (n <= 0) throw StateError('writeFrom made no progress');
    offset += n;
  }
}
