rawtx-rs

A rust-bitcoin based crate making information about Bitcoin transactions accessible.

This includes, for example:

• Detecting input and output types
• SegWit and MulitSig spending
• Explicit BIP-125 Opt In RBF signaling
• BIP-69 compliant
• and more..

In its current state, this crate should be considerd as 'unfinished' and 'under development'.
