Struct Wait 

Source 
pub struct Wait<'a> { /* private fields */ }
Expand description

State to wait for change to a path.

Implementations§

Source§

impl<'a> Wait<'a>

Source

pub fn from_path(path: &'a Path) -> Result<Self>

Construct from a path for change detection. This reads the file stats immediately. If you also need to read the file content to double check whether to “wait” or not, call this before reading the file content to avoid races.

Source

pub fn wait_for_change(&mut self) -> Result<()>

Wait for change on the given path. The path is expected to be atomically updated (ex. inode should change on Linux).

If path does not exist, wait for it to be created.
