Struct ExitCode 

pub struct ExitCode(/* private fields */);

A portable process exit code primitive.

Implementations

impl ExitCode

pub const fn from_u8(code: u8) -> ExitCode

Creates an exit code from an unsigned byte.

pub fn try_from_i32(code: i32) -> Result<ExitCode, ExitCodeError>

Creates an exit code from an i32 when it fits in u8.

Errors

Returns ExitCodeError::OutOfRange when code is outside 0..=255.

pub const fn as_u8(self) -> u8

Returns the exit code as u8.

pub const fn as_i32(self) -> i32

Returns the exit code as i32.

pub const fn is_success(self) -> bool

Returns whether this is a success exit code.

Trait Implementations

impl Clone for ExitCode

fn clone(&self) -> ExitCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExitCode

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

Formats the value using the given formatter.

impl Default for ExitCode

fn default() -> ExitCode

Returns the “default value” for a type.

impl Display for ExitCode

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

Formats the value using the given formatter.

impl Hash for ExitCode

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 Ord for ExitCode

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

fn eq(&self, other: &ExitCode) -> 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 PartialOrd for ExitCode

fn partial_cmp(&self, other: &ExitCode) -> 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.

impl TryFrom<i32> for ExitCode

type Error = ExitCodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<ExitCode, <ExitCode as TryFrom<i32>>::Error>

Performs the conversion.
