Enum CheckedDenom

pub enum CheckedDenom {
    Native(String),
    Cw20(Addr),
}

A denom that has been checked to point to a valid asset. This enum should never be constructed literally and should always be built by calling into_checked on an UncheckedDenom instance.

Variants

Native(String)

A native (bank module) asset.

Cw20(Addr)

A cw20 asset.

Implementations

impl CheckedDenom

pub fn is_cw20(&self, cw20: &Addr) -> bool

Is the CheckedDenom this cw20?

Example

use cosmwasm_std::{Addr, coin};
use cw_denom::CheckedDenom;

let cw20 = Addr::unchecked("fleesp");
assert!(CheckedDenom::Cw20(Addr::unchecked("fleesp")).is_cw20(&cw20));
assert!(!CheckedDenom::Native("fleesp".to_string()).is_cw20(&cw20));

pub fn is_native(&self, denom: &str) -> bool

Is the CheckedDenom this native denom?

Example

use cosmwasm_std::{Addr, coin};
use cw_denom::CheckedDenom;

let coin = coin(10, "floob");
assert!(CheckedDenom::Native("floob".to_string()).is_native(&coin.denom));
assert!(!CheckedDenom::Cw20(Addr::unchecked("floob")).is_native(&coin.denom));

pub fn query_balance<C: CustomQuery>( &self, querier: &QuerierWrapper<'_, C>, who: &Addr, ) -> StdResult<Uint128>

Queries WHO’s balance for the denomination.

pub fn get_transfer_to_message( &self, who: &Addr, amount: Uint128, ) -> StdResult<CosmosMsg>

Gets a CosmosMsg that, when executed, will transfer AMOUNT tokens to WHO. AMOUNT being zero will cause the message execution to fail.

Trait Implementations

impl Clone for CheckedDenom

fn clone(&self) -> CheckedDenom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckedDenom

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CheckedDenom

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CheckedDenom

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

Formats the value using the given formatter.

impl JsonSchema for CheckedDenom

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(generator: &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 CheckedDenom

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
