Enum CfaRule

pub enum CfaRule<T: ReaderOffset> {
    RegisterAndOffset {
        register: Register,
        offset: i64,
    },
    Expression(UnwindExpression<T>),
}

The canonical frame address (CFA) recovery rules.

Variants

RegisterAndOffset

The CFA is given offset from the given register’s value.

Fields

register: Register

The register containing the base value.

offset: i64

The offset from the register’s base value.

Expression(UnwindExpression<T>)

The CFA is obtained by evaluating a DWARF expression program.

Trait Implementations

impl<T: Clone + ReaderOffset> Clone for CfaRule<T>

fn clone(&self) -> CfaRule<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ReaderOffset> Debug for CfaRule<T>

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

Formats the value using the given formatter.

impl<T: ReaderOffset> Default for CfaRule<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq + ReaderOffset> PartialEq for CfaRule<T>

fn eq(&self, other: &CfaRule<T>) -> 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.
