Struct FixedFee

pub struct FixedFee { /* private fields */ }

A wrapper around Coin to help handle fixed fees (with multiples).

Implementations

impl FixedFee

pub fn new(fee: &Coin) -> Self

Creates a wrapped coin to allow charging a fee

pub fn quantity(self, qty: u128) -> Self

Allows to collect the fee multiple times E.g., for namespaces, you want to charge the number of claimed namespaces times the fee for 1 namespace

pub fn assert_payment(self, msg_info: &MessageInfo) -> AbstractResult<Coin>

Validates that the sent funds correspond exactly to the fixed fee Returns the fee object (a.k.a. self) for later use (e.g. transferring the paid fee to another address)

pub fn charge(self, msg_info: &mut MessageInfo) -> AbstractResult<Coin>

Validates that the sent funds include at least the fixed fee This mutates the msg_info so that the rest of the message execution doesn’t include those funds anymore. This acts as a toll on the sent funds Returns the fee object (a.k.a. self) for later use (e.g. transferring the paid fee to another address)

pub fn fee(&self) -> Coin

Trait Implementations

impl Clone for FixedFee

fn clone(&self) -> FixedFee

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FixedFee

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FixedFee

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for FixedFee

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for FixedFee

fn eq(&self, other: &FixedFee) -> 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 FixedFee

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
