Enum nbdkit::FuaFlags

source ·
#[repr(i32)]
pub enum FuaFlags { None, Emulate, Native, }
Expand description

Return values for Server::can_fua

Variants§

§

None

FUA support is not advertised to the client

§

Emulate

The Server::flush callback must work (even if Server::can_flush returns false), and FUA support is emulated by calling Server::flush after any write operation;

§

Native

The Server::write_at, Server::zero, and Server::trim callbacks (if implemented) must handle the flag Flags::FUA, by not returning until that action has landed in persistent storage.
