pub fn spooled_tempfile(max_size: usize) -> SpooledTempFile ⓘ
Expand description
Create a new spooled temporary file.
§Security
This variant is secure/reliable in the presence of a pathological temporary file cleaner.
§Resource Leaking
The temporary file will be automatically removed by the OS when the last handle to it is closed. This doesn’t rely on Rust destructors being run, so will (almost) never fail to clean up the temporary file.
§Examples
use tempfile::spooled_tempfile;
use std::io::Write;
let mut file = spooled_tempfile(15);
writeln!(file, "short line")?;
assert!(!file.is_rolled());
// as a result of this write call, the size of the data will exceed
// `max_size` (15), so it will be written to a temporary file on disk,
// and the in-memory buffer will be dropped
writeln!(file, "marvin gardens")?;
assert!(file.is_rolled());
