pub const PIO_ABI_VERSION: u32 = 3;Expand description
ABI version of this C interface. Bump on any breaking change to an existing
pio_* signature or to the JSON transport schema (new additive symbols don’t
require a bump). A consumer compares pio_abi_version against the value it
was built against (the PIO_ABI_VERSION macro in powerio.h) and refuses a
mismatched library instead of calling in blind.
