Methods from Deref<Target = dyn Layout>

pub fn flatbuffer_writer<'a>( &'a self, ctx: &'a LayoutContext, ) -> impl WriteFlatBuffer<Target<'a> = Layout<'a>> + FlatBufferRoot + 'a

Trait Implementations

impl AsRef<dyn Layout> for StructLayout

fn as_ref(&self) -> &dyn Layout

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for StructLayout

fn clone(&self) -> StructLayout

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StructLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for StructLayout

type Target = dyn Layout

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl IntoLayout for StructLayout

fn into_layout(self) -> LayoutRef

Converts this type into a LayoutRef.
