pub struct Transaction { pub version: u32, pub lock_time: u32, pub input: Vec<TxIn>, pub output: Vec<TxOut>, } A Bitcoin transaction, which describes an authenticated movement of coins. If any inputs have nonempty witnesses, the entire transaction is serialized in the post-BIP141 Segwit format which includes a list of witnesses.

The same applies for u32. On a x86 machine, unsigned int is 32 bits long, so u32 for that machine could be defined as follows: typedef unsigned int u32; You’ll generally find the typedef declaration for these types on a types.h file which corresponds to the architecture you’re compiling your source to.
