breez_sdk_core::bitcoin::blockdata::opcodes

Struct All

pub struct All { /* private fields */ }

Expand description

A script Opcode.

We do not implement Ord on this type because there is no natural ordering on opcodes, but there may appear to be one (e.g. because all the push opcodes appear in a consecutive block) and we don’t want to encourage subtly buggy code. Please use All::classify to distinguish different types of opcodes.

Example of Core bug caused by assuming ordering

Bitcoin Core’s IsPushOnly considers OP_RESERVED to be a “push code”, allowing this opcode in contexts where only pushes are supposed to be allowed.
