Implementations

impl File

pub fn read_binary(&mut self) -> Result<Vec<u8>, IoError>

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>

Once the file has been loaded (see File::is_ready), returns the file content as a String

pub fn is_ready(&mut self) -> bool

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.
