Enum vfs::file::SyncMode

pub enum SyncMode {
    Normal,
    PreClose,
}

Variants

Normal

Used when the Sync fuchsia.io method is used.

PreClose

Used when the connection is about to be closed. Typically this will involve flushing data from caches, but performance is a consideration, so it should only perform what might be necessary for closing the file. If anything must happen when a file is closed, it must be implemented in the Node::close function, not here; a call to sync with this mode is not guaranteed and not implementing/supporting it should have no effect on correctness. If Node::close needs to flush data in an async context, it has to spawn a task. Supporting this mode means that in most cases there’s no need to spawn a task because there should be nothing that needs to be flushed (but it must check). This will only be called if the connection has write permissions; a connection that only has read permissions should not have made any changes that need flushing.

Trait Implementations

impl Default for SyncMode

fn default() -> SyncMode

Returns the “default value” for a type.

impl PartialEq for SyncMode

fn eq(&self, other: &SyncMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
