Module dynamic 

This module provides the entry points to create dynamic transactions, storage and constant lookups.

Structs

DecodedValueThunk

This is the result of making a dynamic request to a node. From this, we can return the raw SCALE bytes that we were handed back, or we can complete the decoding of the bytes into a DecodedValue type.

Value

Value holds a representation of some value that has been decoded, as well as some arbitrary context.

Traits

At

This trait allows indexing into Values (and options of Values) using the At::at() function. It’s a little like Rust’s core::ops::Index trait, but adapted so that we can return and work with optionals.

Functions

constant

Construct a new dynamic constant lookup.

runtime_api_call

Create a new DynamicPayload.

storage

Construct a new dynamic storage lookup.

tx

Construct a transaction at runtime; essentially an alias to DefaultPayload::new() which provides a Composite value for the call data.

Type Aliases

DecodedValue

A scale_value::Value type endowed with contextual information regarding what type was used to decode each part of it. This implements crate::metadata::DecodeWithMetadata, and is used as a return type for dynamic requests.
