Struct libspa::pod::deserialize::PodDeserializer

pub struct PodDeserializer<'de> { /* private fields */ }

This struct is responsible for deserializing a raw pod into a PodDeserialize implementor.

Implementations

impl<'de> PodDeserializer<'de>

pub fn deserialize_from<P: PodDeserialize<'de>>( input: &'de [u8] ) -> Result<(&'de [u8], P), DeserializeError<&'de [u8]>>

Deserialize a PodDeserialize implementor from a raw pod.

Deserialization will only succeed if the raw pod matches the kind of pod expected by the PodDeserialize implementor.

Returns

The remaining input and the type on success, or an error that specifies where parsing failed.

pub unsafe fn deserialize_ptr<P: PodDeserialize<'de>>( ptr: NonNull<spa_pod> ) -> Result<P, DeserializeError<&'de [u8]>>

Deserialize a spa_sys::spa_pod pointer.

Safety

• The provided pointer must point to a valid, well-aligned spa_pod struct.
• The pod pointed to must be kept valid for the entire lifetime of the deserialized object if

pub fn new_array_deserializer<E>( self ) -> Result<(ArrayPodDeserializer<'de, E>, u32), DeserializeError<&'de [u8]>>

where E: FixedSizedPod,

Start parsing an array pod containing elements of type E.

Returns

• The array deserializer and the number of elements in the array on success
• An error if the header could not be parsed

Variant of Self::deserialize_from returning the parsed value as a Value.
