Struct RefCountedTempFile 

pub struct RefCountedTempFile {
    _parent_temp_dir: Arc<TempDir>,
    tempfile: NamedTempFile,
    current_file_disk_usage: u64,
    disk_manager: Arc<DiskManager>,
}

A wrapper around a NamedTempFile that also contains a reference to its parent temporary directory.

Note

After any modification to the underlying file (e.g., writing data to it), the caller must invoke Self::update_disk_usage to update the global disk usage counter. This ensures the disk manager can properly enforce usage limits configured by DiskManager::with_max_temp_directory_size.

Fields

_parent_temp_dir: Arc<TempDir>

The reference to the directory in which temporary files are created to ensure it is not cleaned up prior to the NamedTempFile

tempfile: NamedTempFile

current_file_disk_usage: u64

Tracks the current disk usage of this temporary file. See Self::update_disk_usage for more details.

disk_manager: Arc<DiskManager>

The disk manager that created and manages this temporary file

Implementations

impl RefCountedTempFile

pub fn path(&self) -> &Path

pub fn inner(&self) -> &NamedTempFile

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

Updates the global disk usage counter after modifications to the underlying file.

Errors

• Returns an error if the global disk usage exceeds the configured limit.

pub fn current_disk_usage(&self) -> u64

Trait Implementations

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

Formats the value using the given formatter.

impl Drop for RefCountedTempFile
