Struct age::stream::StreamWriter

source · [−]

pub struct StreamWriter<W> { /* private fields */ }

Expand description

Writes an encrypted age file.

Implementations

source

impl<W: Write> StreamWriter<W>

source

pub fn finish(self) -> Result<W>

Writes the final chunk of the age file.

You MUST call finish when you are done writing, in order to finish the encryption process. Failing to call finish will result in a truncated file that that will fail to decrypt.
