Struct tempfile::NamedTempFileOptions

pub struct NamedTempFileOptions<'a, 'b> {
    // some fields omitted
}

Create a new temporary file with custom parameters.

Example

use tempfile::NamedTempFileOptions;

let named_temp_file = NamedTempFileOptions::new()
                        .prefix("hogehoge")
                        .suffix(".rs")
                        .rand_bytes(5)
                        .create()
                        .unwrap();
let name = named_temp_file.path()
  .file_name().unwrap()
  .to_str().unwrap();

assert!(name.starts_with("hogehoge"));
assert!(name.ends_with(".rs"));
assert_eq!(name.len(), "hogehoge.rs".len() + 5);

Methods
