Function sendFile [src]
Unlike writeSplat and writeVec, this function will call into VTable
even if there is enough buffer capacity for the file contents.
The caller is responsible for flushing. Although the buffer may be bypassed
as an optimization, this is not a guarantee.
Although it would be possible to eliminate error.Unimplemented from the
error set by reading directly into the buffer in such case, this is not
done because it is more efficient to do it higher up the call stack so that
the error does not occur with each write.
See sendFileReading for an alternative that does not have
error.Unimplemented in the error set.
Prototype
pub fn sendFile(w: *Writer, file_reader: *File.Reader, limit: Limit) FileError!usize Parameters
w: *Writerfile_reader: *File.Readerlimit: Limit Possible Errors
Reached the end of the file being read.
Detailed diagnostics are found on the File.Reader struct.
Indicates the caller should do its own file reading; the callee cannot offer a more efficient implementation.
See the Writer implementation for detailed diagnostics.
