}Expand description
Trait implemented by data types that support being serialized to a specific spinel-based byte encoding, based on the marker type.
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 TryPackAs<[u8]> and TryPackAs<SpinelDataWlen>
for handling the D and d Spinel field formats respectively when
serializing.
Required Methods§
Sourcefn try_pack_as<T: Write + ?Sized>(&self, buffer: &mut T) -> Result<usize>
fn try_pack_as<T: Write + ?Sized>(&self, buffer: &mut T) -> Result<usize>
Uses Spinel encoding to serialize to a given std::io::Write reference as the
Spinel type identified by Marker.
Sourcefn pack_as_len(&self) -> Result<usize>
fn pack_as_len(&self) -> Result<usize>
Calculates how many bytes this type will use when serialized.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
