Enum PartnerFee 

pub enum PartnerFee {
    Single(PartnerFeeEntry),
    Multiple(Vec<PartnerFeeEntry>),
}

Partner fee attached to a CoW Protocol order (schema v1.14.0).

Can be a single PartnerFeeEntry or a list of entries. The most common form is a single volume-based entry: PartnerFee::single(PartnerFeeEntry::volume(50, "0x...")).

Use get_partner_fee_bps to extract the first volumeBps value.

Variants

Single(PartnerFeeEntry)

A single fee policy.

Multiple(Vec<PartnerFeeEntry>)

A list of fee policies (one per fee type).

Implementations

impl PartnerFee

pub const fn single(entry: PartnerFeeEntry) -> Self

Convenience constructor for the common single-entry case.

Most integrations use a single fee policy. Wrap a PartnerFeeEntry in PartnerFee::Single for ergonomic use.

Parameters

• entry — the fee policy entry (use PartnerFeeEntry::volume, PartnerFeeEntry::surplus, or PartnerFeeEntry::price_improvement to create one).

Returns

A PartnerFee::Single wrapping the given entry.

Example

use cow_rs::app_data::{PartnerFee, PartnerFeeEntry};

let fee = PartnerFee::single(PartnerFeeEntry::volume(50, "0xAddr"));
assert!(fee.is_single());
assert_eq!(fee.count(), 1);

pub fn entries(&self) -> impl Iterator<Item = &PartnerFeeEntry>

Iterate over all fee entries.

Returns a single-element iterator for Single, or iterates the full vector for Multiple.

Returns

An iterator yielding &PartnerFeeEntry references.

pub const fn is_single(&self) -> bool

Returns true if this is a single-entry partner fee.

pub const fn is_multiple(&self) -> bool

Returns true if this is a multi-entry partner fee.

pub const fn count(&self) -> usize

Returns the number of fee entries: 1 for Single, or the vector length for Multiple.

use cow_rs::app_data::{PartnerFee, PartnerFeeEntry};

let fee = PartnerFee::single(PartnerFeeEntry::volume(50, "0x1234"));
assert_eq!(fee.count(), 1);

let multi = PartnerFee::Multiple(vec![
    PartnerFeeEntry::volume(50, "0x1234"),
    PartnerFeeEntry::surplus(30, 100, "0x5678"),
]);
assert_eq!(multi.count(), 2);
