Struct RefCountedTempFile 

pub struct RefCountedTempFile { /* private fields */ }

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.

This type is Clone-able, allowing multiple references to the same underlying file. The file is deleted only when the last reference is dropped.

The parent temporary directory is also kept alive as long as any reference to this file exists, preventing premature cleanup of the directory.

Once all references to this file are dropped, the file is deleted, and the disk usage is subtracted from the disk manager’s total.

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
