Struct mips::paging::PageTableFlags

pub struct PageTableFlags { /* fields omitted */ }

Possible flags for a page table entry.

VALID      = cp0.entry_lo.valid
WRITABLE   = cp0.entry_lo.dirty
GLOBAL     = cp0.entry_lo.global
CACHEABLE  = cp0.entry_lo.cacheable/uncached
ACCESSED and DIRTY are set by software and used in swap algorithms.
