}Expand description
This is similar to DecodeAsType, except that it’s instead implemented for types that can be given a list of
fields denoting the type being decoded from and attempt to do this decoding. This is generally implemented just
for tuple and struct types, and is automatically implemented via the DecodeAsType macro.
Required Methods§
sourcefn decode_as_fields(
input: &mut &[u8],
fields: &[PortableField],
types: &PortableRegistry
) -> Result<Self, Error>
fn decode_as_fields( input: &mut &[u8], fields: &[PortableField], types: &PortableRegistry ) -> Result<Self, Error>
Given some bytes and some fields denoting their structure, attempt to decode.
Provided Methods§
sourcefn decode_as_field_ids(
input: &mut &[u8],
field_ids: &[PortableFieldId],
types: &PortableRegistry
) -> Result<Self, Error>
fn decode_as_field_ids( input: &mut &[u8], field_ids: &[PortableFieldId], types: &PortableRegistry ) -> Result<Self, Error>
Given some bytes and some field IDs denoting their structure, attempt to decode.
