Struct Scoreboard

pub struct Scoreboard<'a, T>
where
    T: Sized,
{ /* private fields */ }

A wrapper structure for a qemu_plugin_scoreboard *. This is a way of having one entry per VCPU, the count of which is managed automatically by QEMU. Keep in mind that additional entries and existing entries will be allocated and reallocated by qemu, not by the plugin, so every use of a T should include a check for whether it is initialized.

Implementations

impl<'a, T> Scoreboard<'a, T>

pub fn new() -> Self

Allocate a new scoreboard object. This must be freed by calling qemu_plugin_scoreboard_free (or by being dropped).

pub fn find<'b>(&mut self, vcpu_index: VCPUIndex) -> &'b mut MaybeUninit<T>

Returns a reference to entry of a scoreboard matching a given vcpu index. This address is only valid until the next call to get or set.

Trait Implementations

impl<'a, T> Default for Scoreboard<'a, T>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, T> Drop for Scoreboard<'a, T>

fn drop(&mut self)

Executes the destructor for this type.
