Provided methods

fn pointer_size(&self) -> Size[src]

fn machine_usize_max(&self) -> u64[src]

fn machine_isize_min(&self) -> i64[src]

fn machine_isize_max(&self) -> i64[src]

fn truncate_to_ptr(&self, (val, over): (u64, bool)) -> (u64, bool)[src]

Helper function: truncate given value-“overflowed flag” pair to pointer size and update “overflowed flag” if there was an overflow. This should be called by all the other methods before returning!

fn overflowing_offset(&self, val: u64, i: u64) -> (u64, bool)[src]

fn overflowing_signed_offset(&self, val: u64, i: i64) -> (u64, bool)[src]

fn offset<'tcx>(&self, val: u64, i: u64) -> InterpResult<'tcx, u64>[src]

fn signed_offset<'tcx>(&self, val: u64, i: i64) -> InterpResult<'tcx, u64>[src]
