pub struct NibbleSlice<'a> { /* fields omitted */ }
Nibble-orientated view onto byte-slice, allowing nibble-precision offsets.
This is an immutable struct. No operations actually change it.

Create a new nibble slice with the given byte-slice.
Create a new nibble slice with the given byte-slice with a nibble offset.

pub fn iter(&'a self) -> NibbleSliceIterator<'a> | [src] |
Get an iterator for the series of nibbles.
Create a new nibble slice from the given HPE encoded data (e.g. output of encoded()
).
Get the length (in nibbles, naturally) of this slice.
Get the nibble at position i
.
Return object which represents a view on to this slice (further) offset by i
nibbles.

?
How many of the same nibbles at the beginning do we match with them
?
