impl OpenOptions

Methods added by fs-err that are not available on std::fs::OpenOptions.

pub fn from_options(options: OpenOptions) -> Self

Constructs Self from std::fs::OpenOptions

pub fn options(&self) -> &OpenOptions

Returns a reference to the underlying std::fs::OpenOptions.

Note that calling open() on this reference will NOT give you the improved errors from fs-err.

pub fn options_mut(&mut self) -> &mut OpenOptions

Returns a mutable reference to the underlying std::fs::OpenOptions.

This allows you to change settings that don’t yet have wrappers in fs-err. Note that calling open() on this reference will NOT give you the improved errors from fs-err.
