Struct UnwindInfo

pub struct UnwindInfo {
    pub eh_frame: Option<SectionIndex>,
    pub compact_unwind: Option<SectionIndex>,
}

The unwinding information for this Compilation.

It is used for retrieving the unwind information once an exception happens. In the future this structure may also hold other information useful for debugging.

Fields

eh_frame: Option<SectionIndex>

The section index in the Compilation that corresponds to the exception frames. Learn more.

compact_unwind: Option<SectionIndex>

Implementations

impl UnwindInfo

pub fn new(eh_frame: SectionIndex) -> Self

Creates a Dwarf struct with the corresponding indices for its sections

pub fn new_cu(compact_unwind: SectionIndex) -> Self

Trait Implementations

impl Archive for UnwindInfo

where Option<SectionIndex>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedUnwindInfo

The archived representation of this type.

type Resolver = UnwindInfoResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for UnwindInfo

fn clone(&self) -> UnwindInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnwindInfo

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

Formats the value using the given formatter.

impl Default for UnwindInfo

fn default() -> UnwindInfo

Returns the “default value” for a type.

impl<__D: Fallible + ?Sized> Deserialize<UnwindInfo, __D> for Archived<UnwindInfo>

where Option<SectionIndex>: Archive, <Option<SectionIndex> as Archive>::Archived: Deserialize<Option<SectionIndex>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<UnwindInfo, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq<ArchivedUnwindInfo> for UnwindInfo

where Option<SectionIndex>: Archive, <Option<SectionIndex> as Archive>::Archived: PartialEq<Option<SectionIndex>>,

fn eq(&self, other: &ArchivedUnwindInfo) -> 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 PartialEq<UnwindInfo> for ArchivedUnwindInfo

where Option<SectionIndex>: Archive, <Option<SectionIndex> as Archive>::Archived: PartialEq<Option<SectionIndex>>,

fn eq(&self, other: &UnwindInfo) -> 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 PartialEq for UnwindInfo

fn eq(&self, other: &UnwindInfo) -> 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<__S: Fallible + ?Sized> Serialize<__S> for UnwindInfo

where Option<SectionIndex>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
