Struct Pager 

pub struct Pager { /* private fields */ }

A simple pager implementation. One port per pager but a pager can service many files.

Implementations

impl Pager

pub fn new(backing_vmo: Vmo, block_size: u64) -> Result<Self, Errno>

Returns a new pager. block_size shouldn’t be too big (which might cause overflows) and it should be a power of 2.

pub fn start_threads(self: &Arc<Self>)

Starts the pager threads.

pub fn register( &self, name: &str, inode_num: u32, size: u64, extents: Box<[PagerExtent]>, ) -> Result<Vmo, Status>

Registers the file with the pager. Returns a child VMO. extents should be sorted.

pub fn run_pager_thread(&self)

Dedicated thread responsible for listening on port and supplying pages as needed. More than one pager thread can be running concurrently.

pub fn terminate(&self)

Terminates (asynchronously) the pager threads.
