mesh::payload::table::decode

Struct ErasedDecoderEntry

pub struct ErasedDecoderEntry(/* private fields */);
Expand description

An entry in a StructDecodeMetadata::DECODERS table.

Implementations§

§

impl ErasedDecoderEntry

pub unsafe fn read_field<R>( &self, ptr: *mut u8, init: &mut bool, reader: FieldReader<'_, '_, R>, ) -> Result<(), Error>

Reads a field using the decoder metadata.

§Safety

The caller must ensure that the decoder was for resource type R and the object type matches what ptr is pointing to. *init must be set if and only if the field is initialized.

pub unsafe fn default_field( &self, ptr: *mut u8, init: &mut bool, ) -> Result<(), Error>

Initializes a value to its default state using the decoder metadata.

§Safety

The caller must ensure that the decoder was for the object type matching what ptr is pointing to.

pub unsafe fn drop_field(&self, ptr: *mut u8)

Drops a value in place using the decoder metadata.

§Safety

The caller must ensure that the decoder was for the object type matching what ptr is pointing to, and that ptr is ready to be dropped.
