}Expand description
A Rust type that can be decoded from the FIDL type T.
Required Methods§
sourcefn new_empty() -> Self
fn new_empty() -> Self
Creates a valid instance of Self. The specific value does not matter,
since it will be overwritten by decode.
sourceunsafe fn decode(
&mut self,
decoder: &mut Decoder<'_, D>,
offset: usize,
depth: Depth,
) -> Result<(), Error>where
D: ResourceDialect,
unsafe fn decode(
&mut self,
decoder: &mut Decoder<'_, D>,
offset: usize,
depth: Depth,
) -> Result<(), Error>where
D: ResourceDialect,
Decodes an object of type T from the decoder’s buffers into self.
Implementations must validate every byte in
decoder.buf[offset..offset + T::inline_size(decoder.context)] unless
returning an Err value. Implementations that decode out-of-line
objects must call depth.increment()?.
§Safety
Callers must ensure offset is a multiple of T::inline_align and
decoder.buf has room for reading T::inline_size bytes at offset.
Object Safety§
This trait is not object safe.
