Struct frame_support::traits::WrapperOpaque
source · pub struct WrapperOpaque<T>(pub T);
Expand description
A wrapper for any type T
which implement encode/decode in a way compatible with Vec<u8>
.
The encoding is the encoding of T
prepended with the compact encoding of its size in bytes.
Thus the encoded value can be decoded as a Vec<u8>
.
