Struct WriteWatch 

pub struct WriteWatch {
    pub begin: u64,
    pub end: u64,
    pub code: u64,
}

Stops before every store to guest memory whose address lies in begin..=end, with vm.interrupt(code, address, size, value).

The range check is emitted as IR before the store, so a store elsewhere costs three native instructions and no exit. The stored value is passed when it fits an interrupt argument (8 bytes or fewer).

Fields

begin: u64

end: u64

code: u64

Trait Implementations

impl Clone for WriteWatch

fn clone(&self) -> WriteWatch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WriteWatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hook for WriteWatch

fn sites(&mut self, block: &BlockView<'_>) -> Vec<Site>
