Expand description

A simple lock-free radix tree.

Implementations

source

impl<T> PageTable<T>where
T: 'static + Send + Sync,

source

pub fn swap<'g>(
 &self,
 pid: PageId,
 new: Shared<'g, T>,
 guard: &'g Guard
) -> Shared<'g, T>

Atomically swap the previous value in a tree with a new one.

source

pub fn cas<'g>(
 &self,
 pid: PageId,
 old: Shared<'g, T>,
 new: Shared<'g, T>,
 guard: &'g Guard
) -> Result<Shared<'g, T>, Shared<'g, T>>

Compare and swap an old value to a new one.

source

pub fn get<'g>(&self, pid: PageId, guard: &'g Guard) -> Option<Shared<'g, T>>

Try to get a value from the tree.

source

pub fn del<'g>(&self, pid: PageId, guard: &'g Guard) -> Option<Shared<'g, T>>

Delete a value from the tree, returning the old value if it was set.
