Function sendFileReadingAll [src]

Equivalent to sendFileAll but uses direct pread and read calls on file rather than sendFile. This is generally used as a fallback when the underlying implementation returns error.Unimplemented, which is why that error code does not appear in this function's error set. Asserts nonzero buffer capacity.

Prototype

pub fn sendFileReadingAll(w: *Writer, file_reader: *File.Reader, limit: Limit) FileAllError!usize

Parameters

w: *Writerfile_reader: *File.Readerlimit: Limit

Possible Errors

ReadFailed

Detailed diagnostics are found on the File.Reader struct.

WriteFailed

See the Writer implementation for detailed diagnostics.

  pub fn sendFileReadingAll(w: *Writer, file_reader: *File.Reader, limit: Limit) FileAllError!usize {
    var remaining = @intFromEnum(limit);
    while (remaining > 0) {
        remaining -= sendFileReading(w, file_reader, .limited(remaining)) catch |err| switch (err) {
            error.EndOfStream => break,
            else => |e| return e,
        };
    }
    return @intFromEnum(limit) - remaining;
