Struct Txid 

pub struct Txid(/* private fields */);

A bitcoin transaction hash/transaction ID.

For compatibility with the existing Bitcoin infrastructure and historical and current versions of the Bitcoin Core software itself, this and other sha256d::Hash types, are serialized in reverse byte order when converted to a hex string via std::fmt::Display trait operations. See hashes::Hash::DISPLAY_BACKWARD for more details.

Implementations
