#[repr(i8)]
pub enum RustCallStatusCode { Success, Error, UnexpectedError, Cancelled, }
Expand description

Result of a FFI call to a Rust function

Variants§

§

Success

Successful call.

§

Error

Expected error, corresponding to the Result::Err variant. RustCallStatus::error_buf will contain the serialized error.

§

UnexpectedError

Unexpected error. RustCallStatus::error_buf will contain a serialized message string

§

Cancelled

Async function cancelled. RustCallStatus::error_buf will be empty and does not need to be freed.

This is only returned for async functions and only if the bindings code uses the [rust_future_cancel] call.

Trait Implementations§

§

impl PartialEq<RustCallStatusCode> for RustCallStatusCode

§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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