OpenedTempFile

Struct OpenedTempFile 

Source
pub struct OpenedTempFile { /* private fields */ }
Expand description

An already-created provider temporary-file session.

§Examples

use qubit_fs::error::FsResult;
use qubit_fs::metadata::{FileKind, FileMetadata, FileSystemId, OpenedFileInfo};
use qubit_fs::path::Path;
use qubit_fs::spi::TempResourceSpi;
use qubit_fs::spi::OpenedTempFile;

struct EmptyTemp;
impl TempResourceSpi for EmptyTemp {
    fn persist(
        &mut self,
        _: qubit_fs::spi::PersistRequest<'_>,
    ) -> Result<qubit_fs::temp::PersistOutcome, qubit_fs::spi::SpiPersistFailure> {
        unreachable!()
    }
    fn keep(
        &mut self,
    ) -> Result<qubit_fs::temp::PersistOutcome, qubit_fs::spi::SpiPersistFailure> {
        unreachable!()
    }
    fn cleanup(&mut self) -> FsResult<()> {
        Ok(())
    }
}
let info = OpenedFileInfo::new(FileSystemId::new("doc")?, Path::parse("/scratch")?)
    .with_metadata(FileMetadata::new(FileKind::File));
let _opened = OpenedTempFile::new(info, Box::new(EmptyTemp));

Implementations§

Source§

impl OpenedTempFile

Source

pub fn new(info: OpenedFileInfo, session: Box<dyn TempResourceSpi>) -> Self

Wraps an owned temporary-file session.

§Parameters
  • info: Identity and metadata claimed for the temporary file.
  • session: Provider lifecycle session.
§Returns

A temporary-file envelope for facade validation.
