Struct TempFile 

pub struct TempFile<T: Send + Clone + Sized> { /* private fields */ }

Internal struct for handling in-memory files

Implementations

impl<T: Send + Clone + Sized> TempFile<T>

pub fn create<N: AsRef<str>>(name: N) -> TypedResult<Self>

Creates an in-memory file

pub fn seal_read_only(&self) -> TypedResult<TypedMmapMut<'_, T>>

Set the TempFile to read-only (prevents further seal modifications)

pub fn fd(&self) -> RawFd

Returns the raw FD of the TempFile

pub fn write(&self, value: &T) -> TypedResult<()>

Writes value to the TempFile (overwrites existing data, but does not clean)

pub fn read(&self) -> TypedResult<T>

Returns all of the TempFile’s data

pub fn get_typed_mmap_mut(&self) -> TypedResult<TypedMmapMut<'_, T>>

Returns a mutable memory map from a TempFile

pub fn get_typed_mmap(&self) -> TypedResult<TypedMmap<'_, T>>

Returns a memory map from a TemplFile
