Struct rustc_data_structures::temp_dir::MaybeTempDir

source ·

pub struct MaybeTempDir {
    dir: ManuallyDrop<TempDir>,
    keep: bool,
}

Expand description

This is used to avoid TempDir being dropped on error paths unintentionally.

Fields

dir: ManuallyDrop<TempDir>keep: bool

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
