Struct WrapperEntry 

pub struct WrapperEntry {
    pub wrapper_address: String,
    pub wrapper_data: Option<String>,
    pub is_omittable: Option<bool>,
}

A single token wrapper entry.

Fields

wrapper_address: String

Address of the wrapper contract.

wrapper_data: Option<String>

Optional wrapper-specific data.

is_omittable: Option<bool>

Whether this wrapper can be omitted if not needed.

Implementations

impl WrapperEntry

pub fn new(wrapper_address: impl Into<String>) -> Self

Construct a WrapperEntry with just the wrapper contract address.

Wrapper entries describe token wrapping/unwrapping operations applied during order execution (e.g. WETH ↔ ETH).

Parameters

• wrapper_address — 0x-prefixed address of the wrapper contract.

Returns

A new WrapperEntry with wrapper_data and is_omittable unset.

Example

use cow_rs::app_data::types::WrapperEntry;

let w = WrapperEntry::new("0xWrapperContract").with_is_omittable(true);
assert!(w.is_omittable());

pub fn with_wrapper_data(self, data: impl Into<String>) -> Self

Attach wrapper-specific data (e.g. ABI-encoded parameters).

Parameters

• data — opaque data string specific to the wrapper contract.

Returns

self with wrapper_data set.

pub const fn with_is_omittable(self, omittable: bool) -> Self

Mark this wrapper as omittable when not needed.

When true, the settlement contract may skip this wrapper if the wrapping/unwrapping step is unnecessary for the specific execution path.

Parameters

• omittable — whether the wrapper can be skipped.

Returns

self with is_omittable set.

pub const fn has_wrapper_data(&self) -> bool

Returns true if wrapper-specific data is attached.

pub const fn has_is_omittable(&self) -> bool

Returns true if the omittable flag is explicitly set.

pub const fn is_omittable(&self) -> bool

Returns true if this wrapper is explicitly marked as omittable.
