Struct TransferFee 

pub struct TransferFee {
    pub finality_threshold: u32,
    pub minimum_fee: FeeBps,
}

A single fee entry from Circle’s CCTP v2 transfer-fee API.

The API returns an array of entries shaped like:

{ "finalityThreshold": 1000, "minimumFee": 1.3 }

Fields

finality_threshold: u32

Finality threshold this fee applies to.

minimum_fee: FeeBps

Minimum fee in basis points.

Implementations

impl TransferFee

pub const fn new(finality_threshold: u32, minimum_fee: FeeBps) -> Self

Creates a transfer fee entry.

pub const fn finality(self) -> Option<FinalityThreshold>

Returns this entry’s typed finality threshold, if it is one of the thresholds currently recognized by CCTP v2.

pub const fn is_fast_transfer(self) -> bool

Returns true when this entry applies to fast transfers.

pub const fn is_standard_transfer(self) -> bool

Returns true when this entry applies to standard transfers.

pub fn max_fee_with_buffer_percent( self, amount: U256, buffer_percent: u32, ) -> U256

Calculates a maxFee cap in USDC atomic units with the given buffer.

Trait Implementations

impl Clone for TransferFee

fn clone(&self) -> TransferFee

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TransferFee

impl Debug for TransferFee

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransferFee

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TransferFee

impl PartialEq for TransferFee

fn eq(&self, other: &TransferFee) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TransferFee

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
