Struct possum::SnapshotValue

pub struct SnapshotValue<V> { /* private fields */ }

Implementations

impl<V> SnapshotValue<V>

where V: AsRef<Value>,

pub fn view<R>(&self, f: impl FnOnce(&[u8]) -> R) -> Result<R>

pub fn read(&self, buf: &mut [u8]) -> Result<usize>

pub fn new_reader(&self) -> impl Read + '_

pub fn leak_snapshot_dir(&self)

For testing: Leak a reference to the snapshot tempdir so it’s not cleaned up when all references are forgotten. This could possibly be used from internal tests instead.

Trait Implementations

impl<V: Debug> Debug for SnapshotValue<V>

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

Formats the value using the given formatter.

impl<V> Deref for SnapshotValue<V>

type Target = V

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<V> ReadAt for SnapshotValue<V>

where V: AsRef<Value>,

fn read_at(&self, pos: u64, buf: &mut [u8]) -> Result<usize>

Reads bytes from an offset in this source into a buffer, returning how many bytes were read.

fn read_exact_at(&self, pos: u64, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required to fill buf from an offset.
