Struct OrderInteractionHooks 

pub struct OrderInteractionHooks {
    pub version: Option<String>,
    pub pre: Option<Vec<CowHook>>,
    pub post: Option<Vec<CowHook>>,
}

Pre- and post-settlement interaction hooks.

Contains optional lists of CowHook entries that the settlement contract will execute before (pre) and after (post) the trade. When both lists are empty, the field is typically omitted from the JSON.

Example

use cow_app_data::{CowHook, OrderInteractionHooks};

let pre_hook =
    CowHook::new("0x1234567890abcdef1234567890abcdef12345678", "0xabcdef00", "50000");
let hooks = OrderInteractionHooks::new(vec![pre_hook], vec![]);
assert!(hooks.has_pre());
assert!(!hooks.has_post());

Fields

version: Option<String>

Hook schema version.

pre: Option<Vec<CowHook>>

Hooks executed before the settlement.

post: Option<Vec<CowHook>>

Hooks executed after the settlement.

Implementations

impl OrderInteractionHooks

pub fn new(pre: Vec<CowHook>, post: Vec<CowHook>) -> Self

Create hooks with the given pre- and post-execution lists.

Empty vectors are stored as None (omitted from JSON) rather than as empty arrays, matching the TypeScript SDK’s behaviour.

Parameters

• pre — hooks to execute before the settlement trade.
• post — hooks to execute after the settlement trade.

Returns

A new OrderInteractionHooks with version set to None.

Example

use cow_app_data::{CowHook, OrderInteractionHooks};

let pre =
    vec![CowHook::new("0x1234567890abcdef1234567890abcdef12345678", "0x095ea7b3", "50000")];
let hooks = OrderInteractionHooks::new(pre, vec![]);
assert!(hooks.has_pre());
assert!(!hooks.has_post());

pub fn with_version(self, version: impl Into<String>) -> Self

Override the hook schema version.

Parameters

• version — the hook schema version string (e.g. "0.2.0").

Returns

self with version set.

pub fn has_pre(&self) -> bool

Returns true if at least one pre-settlement hook is set.

pub fn has_post(&self) -> bool

Returns true if at least one post-settlement hook is set.
