BufferSizeError

Struct BufferSizeError 

Source
pub struct BufferSizeError {
    pub buf_size: usize,
    pub needed_buf_size: usize,
    pub buffer_kind: BufferKind,
}
Expand description

Insufficient buffer size error.

This is returned by methods like RequestHandle::get_header_names() if a value was larger than the provided maximum size.

If you get such an error, you can try the same call again with a larger buffer.

Fields§

§buf_size: usize

The attempted buffer size.

This is to help make nicer error messages.

§needed_buf_size: usize

The buffer size that was required.

Trying an operation again with a buffer at least this big may succeed where a previous call failed. However, it is not guaranteed to succeed, for example if there is an even larger value later in the list than the first value that was too large.

§buffer_kind: BufferKind

The buffer kind whose size was insufficient.
