Implementations

impl TrapSignal

pub fn iterator() -> impl Iterator<Item = Self>

Returns all possible values of TrapSignal.

pub const fn as_str(self) -> &'static str

Converts TrapSignal into its corresponding signal name as a &'static str

Trait Implementations

impl Clone for TrapSignal

fn clone(&self) -> TrapSignal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Display for TrapSignal

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

Formats the value using the given formatter.

impl FromStr for TrapSignal

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for TrapSignal

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 PartialEq for TrapSignal

fn eq(&self, other: &TrapSignal) -> 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<&str> for TrapSignal

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<TrapSignal> for i32

type Error = TrapSignalNumberError

The type returned in the event of a conversion error.

fn try_from(value: TrapSignal) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<i32> for TrapSignal

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
