Struct StacktrackWriter 

pub struct StacktrackWriter { /* private fields */ }

Writer for the Stacktrack VMO.

Implementations

impl StacktrackWriter

pub unsafe fn new(vmo: &Vmo) -> Result<Self, Error>

Initializes a VMO as an empty table and creates a StacktrackWriter to write into it.

Safety

The caller must guarantee that the vmo is not accessed by others while the returned instance is alive. However, it always safe to take a snapshot and read that instead.

pub fn insert_at_head( &mut self, koid: u64, frames: &[Frame], ) -> Result<NodeIndex, Error>

Inserts a new node at the head of the linked-list.

The index of the new node is returned on success.

pub fn remove(&mut self, node_idx: NodeIndex)

Remove the node at the given index.
