[−][src]Struct uni_app::fs::File
synchronous (native) / asynchronous (web) file API
Methods
impl File[src]
pub fn read_binary(&mut self) -> Result<Vec<u8>, IoError>[src]
Once the file has been loaded (see File::is_ready), returns the file content as Vec<u8>
pub fn read_text(&mut self) -> Result<String, IoError>[src]
Once the file has been loaded (see File::is_ready), returns the file content as a String
pub fn is_ready(&self) -> bool[src]
return true if the file has been loaded
On native target, files are loaded synchronously.
As soon as FileSystem::open returns, the file is ready.
File::read_binary and File::read_text can be called immediately.
On web target, files are loaded asynchronously.
You have to poll File::is_ready until it returns true.
Only then you can call File::read_binary or File::read_text.
