Trait FileWriter 

pub trait FileWriter {
    // Required methods
    fn write_at<'a>(
        &'a mut self,
        offset: u64,
        bytes: &'a [u8],
    ) -> FileWriteFuture<'a>;
    fn set_len(&mut self, len: u64) -> FileWriteFuture<'_>;
    fn finish(self: Box<Self>) -> FileFinishFuture;
}

Writing to a picked file.

Required Methods

fn write_at<'a>( &'a mut self, offset: u64, bytes: &'a [u8], ) -> FileWriteFuture<'a>

fn set_len(&mut self, len: u64) -> FileWriteFuture<'_>

fn finish(self: Box<Self>) -> FileFinishFuture

Ends the writing: on the web the file is replaced only now, and a writer dropped before abandons it; on Android the writes landed in place as they were made.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
