Struct Bridging 

pub struct Bridging {
    pub provider: String,
    pub destination_chain_id: String,
    pub destination_token_address: String,
    pub quote_id: Option<String>,
    pub quote_signature: Option<String>,
    pub attestation_signature: Option<String>,
    pub quote_body: Option<String>,
}

Cross-chain bridging metadata.

Embedded in Metadata when an order was placed via a cross-chain bridge (e.g. Across, Bungee). Records the bridge provider, destination chain, destination token, and optional quote/attestation data so solvers and analytics can trace cross-chain flows.

Example

use cow_app_data::types::Bridging;

let bridging = Bridging::new("across", "42161", "0xTokenOnArbitrum").with_quote_id("quote-123");
assert!(bridging.has_quote_id());

Fields

provider: String

Bridge provider identifier.

destination_chain_id: String

Destination chain ID (as a decimal string).

destination_token_address: String

Destination token contract address.

quote_id: Option<String>

Bridge quote identifier, if available.

quote_signature: Option<String>

Bridge quote signature bytes, if available.

attestation_signature: Option<String>

Bridge attestation signature bytes, if available.

quote_body: Option<String>

Opaque bridge quote body, if available.

Implementations

impl Bridging

pub fn new( provider: impl Into<String>, destination_chain_id: impl Into<String>, destination_token_address: impl Into<String>, ) -> Self

Construct a Bridging record with the three required fields.

Optional fields (quote ID, signatures, quote body) can be attached afterwards via the with_* builder methods.

Parameters

• provider — bridge provider identifier (e.g. "across", "bungee").
• destination_chain_id — target chain ID as a decimal string (e.g. "42161" for Arbitrum One).
• destination_token_address — 0x-prefixed contract address of the token on the destination chain.

Returns

A new Bridging with all optional fields set to None.

Example

use cow_app_data::types::Bridging;

let b = Bridging::new("across", "42161", "0xTokenOnArbitrum");
assert_eq!(b.provider, "across");
assert!(!b.has_quote_id());

pub fn with_quote_id(self, id: impl Into<String>) -> Self

Attach a bridge quote identifier.

Parameters

• id — the quote identifier returned by the bridge provider.

Returns

self with quote_id set.

pub fn with_quote_signature(self, sig: impl Into<String>) -> Self

Attach a bridge quote signature.

Parameters

• sig — the hex-encoded signature bytes from the bridge provider.

Returns

self with quote_signature set.

pub fn with_attestation_signature(self, sig: impl Into<String>) -> Self

Attach an attestation signature.

Parameters

• sig — the hex-encoded attestation signature bytes.

Returns

self with attestation_signature set.

pub fn with_quote_body(self, body: impl Into<String>) -> Self

Attach an opaque bridge quote body.

Parameters

• body — the raw quote body string from the bridge provider.

Returns

self with quote_body set.

pub const fn has_quote_id(&self) -> bool

Returns true if a bridge quote identifier is set.

pub const fn has_quote_signature(&self) -> bool

Returns true if a bridge quote signature is set.

pub const fn has_attestation_signature(&self) -> bool

Returns true if an attestation signature is set.

pub const fn has_quote_body(&self) -> bool

Returns true if an opaque quote body is set.
