Implementations

impl Cursor

pub fn coredump(
    address_space: &mut AddressSpace,
    state: &CoredumpState
) -> Result<Cursor, Error>

Method constructs cursor for coredump unwinding.

Arguments

• address_space - configured AddressSpace

• state - Configured CoredumpState

pub fn local<F, T>(f: F) -> Result<T, Error> where
    F: FnOnce(Cursor) -> Result<T, Error>, 

Method constructs cursor for local unwinding.

Arguments

• f - function to work with local cursor

pub fn step(&mut self) -> Result<bool, Error>

Method executes step on cursor.

Return

• true - if step is executed

• false - if cursor ends

• Error - if error while steping is occured
