Enum neotron_common_bios::FfiResult

#[repr(C)]
pub enum FfiResult<T, E> {
    Ok(T),
    Err(E),
}

All API functions which can fail return this type.

We don’t use the Result type from the standard library because that isn’t FFI safe and may change layout between compiler versions.

Variants

Ok(T)

The operation succeeded (like core::result::Result::Ok).

Err(E)

The operation failed (like core::result::Result::Err).

Implementations

impl<T, E> FfiResult<T, E>

pub fn unwrap(self) -> T

where E: Debug,

Obtain the inner value, or panic - just like core::Result::unwrap.

Trait Implementations

impl<T, E> Clone for FfiResult<T, E>

where T: Clone, E: Clone,

fn clone(&self) -> FfiResult<T, E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, E> Debug for FfiResult<T, E>

where T: Debug, E: Debug,

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

Formats the value using the given formatter.

impl<T, E> From<Result<T, E>> for FfiResult<T, E>

fn from(value: Result<T, E>) -> FfiResult<T, E>

Converts to this type from the input type.

impl<T, E> Hash for FfiResult<T, E>

where T: Hash, E: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T, E> Ord for FfiResult<T, E>

where T: Ord, E: Ord,

fn cmp(&self, other: &FfiResult<T, E>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<T, E> PartialEq for FfiResult<T, E>

where T: PartialEq, E: PartialEq,

fn eq(&self, other: &FfiResult<T, E>) -> bool

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

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.

impl<T, E> PartialOrd for FfiResult<T, E>

where T: PartialOrd, E: PartialOrd,

fn partial_cmp(&self, other: &FfiResult<T, E>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T, E> Eq for FfiResult<T, E>

where T: Eq, E: Eq,

impl<T, E> StructuralPartialEq for FfiResult<T, E>
