Struct gimli::read::Augmentation

pub struct Augmentation {
    lsda: Option<DwEhPe>,
    personality: Option<(DwEhPe, Pointer)>,
    fde_address_encoding: Option<DwEhPe>,
    is_signal_trampoline: bool,
}

We support the z-style augmentation defined by .eh_frame.

Fields

lsda: Option<DwEhPe>

A ‘L’ may be present at any position after the first character of the string. This character may only be present if ‘z’ is the first character of the string. If present, it indicates the presence of one argument in the Augmentation Data of the CIE, and a corresponding argument in the Augmentation Data of the FDE. The argument in the Augmentation Data of the CIE is 1-byte and represents the pointer encoding used for the argument in the Augmentation Data of the FDE, which is the address of a language-specific data area (LSDA). The size of the LSDA pointer is specified by the pointer encoding used.

personality: Option<(DwEhPe, Pointer)>

A ‘P’ may be present at any position after the first character of the string. This character may only be present if ‘z’ is the first character of the string. If present, it indicates the presence of two arguments in the Augmentation Data of the CIE. The first argument is 1-byte and represents the pointer encoding used for the second argument, which is the address of a personality routine handler. The size of the personality routine pointer is specified by the pointer encoding used.

fde_address_encoding: Option<DwEhPe>

A ‘R’ may be present at any position after the first character of the string. This character may only be present if ‘z’ is the first character of the string. If present, The Augmentation Data shall include a 1 byte argument that represents the pointer encoding for the address pointers used in the FDE.

is_signal_trampoline: bool

True if this CIE’s FDEs are trampolines for signal handlers.

Implementations

impl Augmentation

fn parse<Section, R>( augmentation_str: &mut R, bases: &BaseAddresses, address_size: u8, section: &Section, input: &mut R, ) -> Result<Augmentation>

where R: Reader, Section: UnwindSection<R>,

Trait Implementations

impl Clone for Augmentation

fn clone(&self) -> Augmentation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Augmentation

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

Formats the value using the given formatter.

impl Default for Augmentation

fn default() -> Augmentation

Returns the “default value” for a type.

impl PartialEq for Augmentation

fn eq(&self, other: &Augmentation) -> 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.
