Implementations

impl es_return_t

Variants available from macOS 10.15.0 onwards

pub const ES_RETURN_SUCCESS: es_return_t

Function was successful

pub const ES_RETURN_ERROR: es_return_t

Function failed

Last value for macOS 10.15.0

pub const LAST_10_15_0: es_return_t = es_return_t::ES_RETURN_ERROR

Easily identifiable name for the last member of macOS 10.15.0

impl es_return_t

pub fn ok(self) -> Result<(), ReturnError>

Converts an instance of es_return_t to a Result<(), ReturnError>

Trait Implementations

impl Clone for es_return_t

fn clone(&self) -> es_return_t

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for es_return_t

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

Formats the value using the given formatter.

impl Hash for es_return_t

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

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 Ord for es_return_t

fn cmp(&self, other: &es_return_t) -> 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,

Restrict a value to a certain interval.

impl PartialEq for es_return_t

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

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

const 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 PartialOrd for es_return_t

fn partial_cmp(&self, other: &es_return_t) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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