sizeHint method
If possible give a hint of expected size of the encoding.
This method is used inside default implementation of encode
to avoid re-allocations.
Implementation
@override
int sizeHint(Map<K, V> value) {
var size = CompactCodec.codec.sizeHint(value.length);
for (final entry in value.entries) {
size += keyCodec.sizeHint(entry.key);
size += valueCodec.sizeHint(entry.value);
}
return size;
}
