Expand description

An error that can occur deep in a decoder This type is kept very small so that function that use it inline often

Variants

`InsufficientBytes`

Insufficient data in the buffer for a read operation

`InvalidPreviousIndex`

slice_from was called with an invalid index

`PointerNotPriorToLabel`

Fields

idx: usize

index of the label containing this pointer

ptr: u16

location to which the pointer is directing

Pointer points to an index within or after the current label

`LabelBytesTooLong(usize)`

Label bytes exceeded the limit of 63

`UnrecognizedLabelCode(u8)`

An unrecognized label code was found

`DomainNameTooLong(usize)`

A domain name was too long

`LabelOverlapsWithOther`

Fields

label: usize

Start of the label that is overlaps

other: usize

Start of the other label

Overlapping labels
