Struct subxt::constants::ConstantsClient

pub struct ConstantsClient<T, Client> { /* private fields */ }

A client for accessing constants.

Implementations

impl<T, Client> ConstantsClient<T, Client>

pub fn new(client: Client) -> Self

Create a new ConstantsClient.

impl<T: Config, Client: OfflineClientT<T>> ConstantsClient<T, Client>

pub fn validate<Address: ConstantAddress>(
    &self,
    address: &Address
) -> Result<(), Error>

Run the validation logic against some constant address you’d like to access. Returns Ok(()) if the address is valid (or if it’s not possible to check since the address has no validation hash). Return an error if the address was not valid or something went wrong trying to validate it (ie the pallet or constant in question do not exist at all).

pub fn at<Address: ConstantAddress>(
    &self,
    address: &Address
) -> Result<<Address::Target as DecodeWithMetadata>::Target, Error>

Access the constant at the address given, returning the type defined by this address. This is probably used with addresses given from static codegen, although you can manually construct your own, too.

Trait Implementations

impl<T, Client> Clone for ConstantsClient<T, Client>where
    Client: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.
