Struct Prevalidated

pub struct Prevalidated { /* private fields */ }

HeaderEntry attribute identifying those that have been prevalidated.

The specification of a header entry identified by this discriminant doesn’t return a Result.

Example

This example adds the header name custom-header and value custom:some-value.

use unc_jsonrpc_client::{
    header::{HeaderEntry, HeaderValue, Prevalidated},
    methods, JsonRpcClient,
};

struct CustomHeader(HeaderValue);

impl HeaderEntry<Prevalidated> for CustomHeader {
    type HeaderName = &'static str;
    type HeaderValue = HeaderValue;

    fn header_name(&self) -> &Self::HeaderName {
        &"custom-header"
    }

    fn header_pair(self) -> (Self::HeaderName, Self::HeaderValue) {
        ("custom-header", self.0)
    }
}

let header_value = HeaderValue::try_from("custom:some-value")?; // <- error handling here

let client = JsonRpcClient::connect("https://rpc.testnet.unc.org").header(CustomHeader(header_value));
