[][src]Struct tempfile::SpooledTempFile

pub struct SpooledTempFile { /* fields omitted */ }

An object that behaves like a regular temporary file, but keeps data in memory until it reaches a configured size, at which point the data is written to a temporary file on disk, and further operations use the file on disk.
