Enum cargo::core::profiles::PanicSetting

enum PanicSetting {
    AlwaysUnwind,
    ReadProfile,
}

How Cargo processes the panic setting or profiles.

This is done to handle test/benches inheriting from dev/release, as well as forcing for_host units to always unwind. It also interacts with -Z panic-abort-tests.

Variants

AlwaysUnwind

Used to force a unit to always be compiled with the panic=unwind strategy, notably for build scripts, proc macros, etc.

ReadProfile

Indicates that this unit will read its profile setting and use whatever is configured there.

Trait Implementations

impl Clone for PanicSetting

fn clone(&self) -> PanicSetting

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PanicSetting

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

Formats the value using the given formatter.

impl Hash for PanicSetting

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 PanicSetting

fn cmp(&self, other: &PanicSetting) -> 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 PartialEq for PanicSetting

fn eq(&self, other: &PanicSetting) -> 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 PanicSetting

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
