Struct SpendRequestBuilder 

pub struct SpendRequestBuilder<SrcAddressType, DstAddressType> { /* private fields */ }

Configures a cross-chain spend request.

Pass the completed builder to TridentClient::spend to submit the intent. The client fills in the source spender address, salt, and fee estimation automatically.

Implementations

impl<SrcAddressType, DstAddressType> SpendRequestBuilder<SrcAddressType, DstAddressType>

pub const fn src_domain(&self) -> Domain

Returns the source domain.

pub const fn dst_domain(&self) -> Domain

Returns the destination domain.

pub const fn max_fee(&self) -> Option<U256>

Returns the explicit max fee, or None if it will be auto-estimated.

pub const fn expiry_height(&self) -> Option<u64>

Returns the explicit expiry height, or None if it will be auto-resolved.

impl<SrcAddressType, DstAddressType> SpendRequestBuilder<SrcAddressType, DstAddressType>

where SrcAddressType: ChainAddress, DstAddressType: ChainAddress,

pub fn new( src_domain: Domain, src_token: SrcAddressType, dst_domain: Domain, dst_token: DstAddressType, dst_recipient: DstAddressType, amount: U256, ) -> Self

Creates a new builder for a spend from src_domain/src_token to dst_domain/dst_token, paying dst_recipient the given amount.

max_fee, expiry_height, and caller default to unset and can be configured via the corresponding with_* methods; if left unset, the client auto-resolves them when the request is submitted.

pub fn with_max_fee(self, max_fee: U256) -> Self

Sets an explicit max fee, skipping server-side fee estimation.

pub fn with_expiry_height(self, expiry_height: u64) -> Self

Sets an explicit expiry block height for the spend intent.

When omitted, the client auto-resolves the expiry by querying the server’s spend_intent_min_expiry_height and adding the source domain’s configured margin (set on the builder via crate::TridentClientBuilder::with_expiry_margin). Domains without an explicit margin fall back to 10% of the server’s minimum.

pub fn with_caller(self, caller: DstAddressType) -> Self

Sets the on-chain caller for the destination-side execution. Defaults to the zero address when not set.
