Struct ChangedJsonFile 

pub struct ChangedJsonFile<R>
where
    R: DeserializeOwned,
{ /* private fields */ }

A wrapper around JsonFile which can be used to read the contents of a file and only return the contents if they have changed since the last read.

Implementations

impl<R> ChangedJsonFile<R>

where R: DeserializeOwned + PartialEq,

pub fn new<P: AsRef<Path>>( path: P, unblocker: impl Into<Arc<dyn Unblocker>>, ) -> Result<ChangedJsonFile<R>, LogFSError>

Opens the file at the provided path and returns a ChangedJsonFile which can be used to read the contents of the file.

pub fn content(&mut self) -> Result<Option<R>, LogFSError>

Returns the current contents of the file as a deserialized object, or None if the contents haven’t changed since the last read or if the file is empty (which happens when the game clears the file before it starts to write.)

pub async fn content_async(&mut self) -> Result<Option<R>, LogFSError>

Available on crate feature asynchronous only.

The same as ChangedJsonFile::content, but asynchronous.
