TradingWithdrawIntentPayload is the client-signed typed withdraw request. Account scope and backend intent ids are derived server-side.

Fields

action: EnumValue<TradingWithdrawAction>

Destination for funds leaving Trading.

Field 1: action

asset_id: u32

Unified asset identifier from Polyester asset metadata. amount_e18 is denominated in this asset at canonical 18-decimal scale.

Field 2: asset_id

destination_chain_id: u64

External network id for TO_EXTERNAL_CHAIN. Omit for TO_FUNDING.

Field 3: destination_chain_id

amount_e18: MessageFieldView<U128View<'a>>

Withdraw amount in canonical 18-decimal unified asset units. For example, 0.5 is encoded as 500000000000000000.

Field 4: amount_e18

deadline_ts_sec: u64

Unix timestamp in seconds after which this signed user authorization is no longer accepted by the API. This is separate from the server-owned execution deadline used later for on-chain submission.

Field 5: deadline_ts_sec

nonce: MessageFieldView<U128View<'a>>

Client-generated unsigned 128-bit nonce bound to the signed request. This is an identifier, not a decimal amount.

Field 6: nonce

destination_address: &'a str

Destination address. For TO_EXTERNAL_CHAIN this is an address on destination_chain_id and is validated according to that network. For TO_FUNDING, omit it to move funds to the selected account’s Funding account or provide another Polyester funding address for a Trading-to-Funding transfer.

Field 7: destination_address

idempotency_key: &'a str

Client-chosen idempotency key. Reusing the same key with the same payload returns the existing withdraw; reusing it with different payload fails.

Field 8: idempotency_key

__buffa_unknown_fields: UnknownFieldsView<'a>

Trait Implementations

impl<'a> Clone for TradingWithdrawIntentPayloadView<'a>

fn clone(&self) -> TradingWithdrawIntentPayloadView<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for TradingWithdrawIntentPayloadView<'a>

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

Formats the value using the given formatter.

impl<'a> Default for TradingWithdrawIntentPayloadView<'a>

fn default() -> TradingWithdrawIntentPayloadView<'a>

Returns the “default value” for a type.

impl<'v> DefaultViewInstance for TradingWithdrawIntentPayloadView<'v>

fn default_view_instance<'a>() -> &'a Self

where Self: 'a,

Return a reference to the single default view instance.

impl<'a> MessageName for TradingWithdrawIntentPayloadView<'a>

const PACKAGE: &'static str = "chain.withdraw.v1"

The protobuf package the message is declared in.

const NAME: &'static str = "TradingWithdrawIntentPayload"

The unqualified message name, with . between nesting levels.

const FULL_NAME: &'static str = "chain.withdraw.v1.TradingWithdrawIntentPayload"

The fully-qualified protobuf type name with no leading dot.

const TYPE_URL: &'static str = "type.googleapis.com/chain.withdraw.v1.TradingWithdrawIntentPayload"

The google.protobuf.Any.type_url form for this message.

impl<'a> MessageView<'a> for TradingWithdrawIntentPayloadView<'a>

type Owned = TradingWithdrawIntentPayload

The corresponding owned message type.

fn decode_view(buf: &'a [u8]) -> Result<Self, DecodeError>

Decode a view from a buffer, borrowing string/bytes fields directly.

fn decode_view_with_ctx( buf: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<Self, DecodeError>

Decode a view under custom decode limits.

fn merge_view_field( &mut self, tag: Tag, cur: &'a [u8], before_tag: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<&'a [u8], DecodeError>

Decode one field’s payload into this view (generated per message).

fn to_owned_message(&self) -> Result<TradingWithdrawIntentPayload, DecodeError>

Convert this view to the owned message type.

fn to_owned_from_source( &self, __buffa_src: Option<&Bytes>, ) -> Result<TradingWithdrawIntentPayload, DecodeError>

Convert this view to the owned message type, optionally slicing bytes::Bytes-typed fields from source instead of copying.

fn decode_view_ctx( buf: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<Self, DecodeError>

where Self: Default,

Decode a view under an explicit DecodeContext (remaining recursion depth and unknown-field allowance), driving the provided tag loop over merge_view_field.

fn merge_into_view( &mut self, buf: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<(), DecodeError>

Merge fields from buf into this view (proto merge semantics): repeated fields append, singular fields last-wins, singular message fields merge recursively.

impl<'__a> Serialize for TradingWithdrawIntentPayloadView<'__a>

Serializes this view as protobuf JSON.

Implicit-presence fields with default values are omitted, required fields are always emitted, explicit-presence (optional) fields are emitted only when set, bytes fields are base64-encoded, and enum values are their proto name strings.

This impl uses serialize_map(None) because the number of emitted fields depends on default-omission rules; serializers that require known map lengths (e.g. bincode) will return a runtime error. Use the owned message type for those formats.

fn serialize<__S: Serializer>(&self, __s: __S) -> Result<__S::Ok, __S::Error>

Serialize this value into the given Serde serializer.

impl<'a> ViewEncode<'a> for TradingWithdrawIntentPayloadView<'a>

fn compute_size(&self, __cache: &mut SizeCache) -> u32

Compute the encoded byte size of this view, recording nested sub-message sizes in cache for write_to to consume.

fn write_to(&self, __cache: &mut SizeCache, buf: &mut impl BufMut)

Write this view’s encoded bytes to a buffer, consuming nested-message sizes from cache (populated by a prior compute_size call on the same cache).

fn encode(&self, buf: &mut impl BufMut)

Compute size, then write. Primary view-encode entry point.

fn encode_with_cache(&self, cache: &mut SizeCache, buf: &mut impl BufMut)

Encode using a caller-supplied SizeCache, for reuse across many encodes in a hot loop. Clears the cache first.

fn encoded_len(&self) -> u32

Compute the encoded byte size of this view.

fn encode_length_delimited(&self, buf: &mut impl BufMut)

Encode this view as a length-delimited byte sequence.

fn encode_to_vec(&self) -> Vec<u8>

Encode this view to a new Vec<u8>.

fn encode_to_bytes(&self) -> Bytes

Encode this view to a new bytes::Bytes.

impl ViewReborrow for TradingWithdrawIntentPayloadView<'static>

type Reborrowed<'b> = TradingWithdrawIntentPayloadView<'b>

The same view type with its lifetime shortened to 'b.

fn reborrow<'b>(this: &'b Self) -> &'b Self::Reborrowed<'b>

Coerce &'b Self (= &'b FooView<'static>) to &'b Self::Reborrowed<'b> (= &'b FooView<'b>). The canonical body is just this; the compiler accepts it via standard lifetime variance for covariant view types.
