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.

Implementations

impl RefCountedTempFile

pub fn path(&self) -> &Path

pub fn inner(&self) -> &NamedTempFile

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

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.
