Struct OpenOptions 

pub struct OpenOptions { /* private fields */ }

Options for opening a mapped region.

These options must be consistent across all processes that open the same backing file. For example, if a creator initializes without blocking and a joiner requests blocking, opening fails with a layout compatibility error.

Implementations

impl OpenOptions

pub fn new() -> Self

Create default open options.

pub fn path(self, path: impl Into<PathBuf>) -> Self

Use a specific file path for the mapping.

pub fn blocking(self, enabled: bool) -> Self

Enable appended wake sections and set INDEXBUS_CAP_SUPPORTS_BLOCKING.

All participants that open the same backing file should agree on this flag.
