}Expand description
Trait for unpacking a spinel-encoded buffer to a specific type when the field type is known.
The generic parameter Marker is effectiely a part of the name of the
trait and is not used directly by the trait. Types may implement more than
one instance of this trait, each with a different marker type.
For example, structs that use the spinel_packed attribute macro
will implement both TryUnpackAs<[u8]> and TryUnpackAs<SpinelDataWlen>
for handling the D and d Spinel field formats respectively when
deserializing.
Required Methods§
Sourcefn try_unpack_as(iter: &mut Iter<'a, u8>) -> Result<Self>
fn try_unpack_as(iter: &mut Iter<'a, u8>) -> Result<Self>
Attempts to decode the data (with a format determined by Marker) at the given
iterator into an instance of Self.
Provided Methods§
Sourcefn try_unpack_as_from_slice(slice: &'a [u8]) -> Result<Self>
fn try_unpack_as_from_slice(slice: &'a [u8]) -> Result<Self>
Convenience method for unpacking directly from a borrowed slice.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
