impl<'a, 'b> Snapshot<'a, 'b>

pub fn new(destination: &'a Path, memory_ranges: Vec<Range<u64>>) -> Self

Create a new memory snapshot.

The default version implements the LiME format.

pub fn max_disk_usage_percentage( self, max_disk_usage_percentage: Option<f64>, ) -> Self

Specify the maximum disk usage to stay under as a percentage

This is an estimation, calculated at start time

pub fn max_disk_usage(self, max_disk_usage: Option<NonZeroU64>) -> Self

Specify the maximum disk space in MB to use

This is an estimation, calculated at start time

pub fn source(self, source: Option<&'b Source>) -> Self

Specify the source for creating the snapshot

pub fn version(self, version: u32) -> Self

Specify the version of the snapshot format

pub fn create(&self) -> Result<(), Error>

Create a memory snapshot
