Enum AbiCheck 

pub enum AbiCheck {
    Match,
    Missing,
    Mismatch {
        found: u32,
    },
}

Outcome of reading a freshly instantiated guest’s ABI version.

Variants

Match

The guest advertises HOST_ABI_VERSION; it is safe to call.

Missing

The guest does not export __rustledger_abi_version (built without the wasm_*_main! macros, or against a plugin-types from before the handshake existed), or the export trapped / has the wrong signature. Either way the host can’t confirm compatibility, so the guest is rejected.

Mismatch

The guest advertises a different ABI version than the host.

Fields

found: u32

Version the guest reported.

Trait Implementations

impl Clone for AbiCheck

fn clone(&self) -> AbiCheck

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for AbiCheck

impl Debug for AbiCheck

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for AbiCheck

impl PartialEq for AbiCheck

fn eq(&self, other: &AbiCheck) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
