Enum ExpectedLen 

pub enum ExpectedLen {
    Exact(usize),
    AtLeast(usize),
    OneOf(&'static [usize]),
    Multiple(usize),
}

What length(s) a Data Item is permitted to take on the wire, used for CodecError::InvalidDataItemLength reporting. Several DLEP Data Items are not fixed-width — Connection Points are 5 or 7, Status / Peer Type are “at least 1”, Extensions Supported is a multiple of 2 — so a single expected: usize would be misleading.

Variants

Exact(usize)

Length must be exactly this value.

AtLeast(usize)

Length must be at least this value.

OneOf(&'static [usize])

Length must be one of the listed values.

Multiple(usize)

Length must be a non-negative multiple of this value.
