Enum CallbackResult

#[repr(i32)]
pub enum CallbackResult {
    Success = 0,
    Error = 1,
    UnexpectedError = 2,
}

Result of a foreign callback invocation

Variants

Success = 0

Successful call. The return value is serialized to buf_ptr.

Error = 1

Expected error. This is returned when a foreign method throws an exception that corresponds to the Rust Err half of a Result. The error value is serialized to buf_ptr.

UnexpectedError = 2

Unexpected error. An error message string is serialized to buf_ptr.

Trait Implementations

impl Debug for CallbackResult

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

Formats the value using the given formatter.

impl PartialEq for CallbackResult

fn eq(&self, other: &CallbackResult) -> 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.

impl TryFrom<i32> for CallbackResult

type Error = i32

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<CallbackResult, i32>

Performs the conversion.

impl Eq for CallbackResult
