Struct storage_proofs_core::data::Data

pub struct Data<'a> { /* fields omitted */ }

A wrapper around data either on disk or a slice in memory, that can be dropped and read back into memory, to allow for better control of memory consumption.

Implementations

impl<'a> Data<'a>

pub fn from_path(path: PathBuf) -> Self

pub fn new(raw: &'a mut [u8], path: PathBuf) -> Self

pub fn is_empty(&self) -> bool

pub fn ensure_data(&mut self) -> Result<()>

Recover the data.

pub fn drop_data(&mut self)

Drops the actual data, if we can recover it.
