Struct mfio_rt::native::NativeRtBuilder

pub struct NativeRtBuilder { /* private fields */ }

Available on crate feature native only.

Builder for the NativeRt.

This builder allows configuring the I/O backends to try to construct for the filesystem handle. Note that the order of backends is fixed, and is as follows:

• iocp
• thread

The full order (including unsupported/disabled backends) is as follows:

• io_uring
• iocp
• mio
• thread

If you wish to customize the construction order, please use multiple builders.

Implementations

impl NativeRtBuilder

pub fn all_backends() -> Self

Get a NativeRtBuilder with all backends enabled.

pub fn env_backends() -> Self

Get a NativeRtBuilder with backends specified by environment.

This function attempts to parse MFIO_FS_BACKENDS environment variable and load backends specified by it. If the environment variable is not present, or non-unicode, this function falls back to using all_backends.

pub fn enable_all(self) -> Self

pub fn iocp(self, iocp: bool) -> Self

Available on non-miri and Windows and crate feature iocp only.

Enables the iocp backend.

pub fn thread(self, thread: bool) -> Self

Enables the thread backend.

pub fn build(self) -> Result<NativeRt>

pub fn build_each(self) -> Vec<(&'static str, Result<NativeRt>)>
