Struct cw20::Cw20Contract

pub struct Cw20Contract(pub HumanAddr);

Cw20Contract is a wrapper around HumanAddr that provides a lot of helpers for working with this.

If you wish to persist this, convert to Cw20CanonicalContract via .canonical()

Implementations

impl Cw20Contract

pub fn addr(&self) -> HumanAddr

pub fn canonical<A: Api>(&self, api: &A) -> StdResult<Cw20CanonicalContract>

Convert this address to a form fit for storage

pub fn call<T: Into<Cw20HandleMsg>>(&self, msg: T) -> StdResult<CosmosMsg>

pub fn balance<Q: Querier>(
    &self,
    querier: &Q,
    address: HumanAddr
) -> StdResult<Uint128>

Get token balance for the given address

pub fn meta<Q: Querier>(&self, querier: &Q) -> StdResult<TokenInfoResponse>

Get metadata from the contract. This is a good check that the address is a valid Cw20 contract.

pub fn allowance<Q: Querier>(
    &self,
    querier: &Q,
    owner: HumanAddr,
    spender: HumanAddr
) -> StdResult<AllowanceResponse>

Get allowance of spender to use owner's account

pub fn minter<Q: Querier>(
    &self,
    querier: &Q
) -> StdResult<Option<MinterResponse>>

Find info on who can mint, and how much

pub fn has_allowance<Q: Querier>(&self, querier: &Q) -> bool

returns true if the contract supports the allowance extension

pub fn is_mintable<Q: Querier>(&self, querier: &Q) -> bool

returns true if the contract supports the mintable extension
