Used to select how the read should be handled.

pub const ReadBuffer = union(enum)

Code

pub const ReadBuffer = union(enum) {
    /// io_uring will read directly into this buffer
    buffer: []u8,

    /// io_uring will read directly into these buffers using readv.
    iovecs: []const posix.iovec,

    /// io_uring will select a buffer that has previously been provided with `provide_buffers`.
    /// The buffer group reference by `group_id` must contain at least one buffer for the read to work.
    /// `len` controls the number of bytes to read into the selected buffer.
