Struct TransactionPayloadDecoder

pub struct TransactionPayloadDecoder<'a> { /* private fields */ }

Decoder for transaction payload created using TransactionPayloadBuilder.

Implementations

impl<'a> TransactionPayloadDecoder<'a>

pub fn new( payload: &'a [u128], external_args_buffer: &'a mut [*mut c_void], output_buffer: &'a mut [MaybeUninit<u128>], output_buffer_offsets: &'a mut [MaybeUninit<(u32, u32)>], map_context: fn(TransactionMethodContext) -> MethodContext, ) -> Self

Create new instance.

The size of external_args_buffer defines max number of bytes allocated for ExternalArgs, which impacts the number of arguments that can be represented by ExternalArgs. The size is specified in pointers with #[slot] argument using one pointer, #[input] two pointers and #[output] three pointers each.

The size of output_buffer defines how big the total size of #[output] and return values could be in all methods of the payload together.

The size of output_buffer_offsets defines how many #[output] arguments and return values could exist in all methods of the payload together.

impl<'a> TransactionPayloadDecoder<'a>

pub fn decode_next_method( &mut self, ) -> Result<Option<PreparedMethod<'_>>, TransactionPayloadDecoderError>

Decode the next method (if any) in the payload

pub unsafe fn decode_next_method_unchecked( &mut self, ) -> Option<PreparedMethod<'_>>

Decode the next method (if any) in the payload without checking size.

Safety

Must be used with trusted input created using TransactionPayloadBuilder or pre-verified using Self::decode_next_method() earlier.

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

Formats the value using the given formatter.
