Crate fin_model

A comprehensive data model for various financial data.

The purpose of this API is to construct a comprehensive data model for company and market financial information in a coherent and idiomatic manner, not of a specific service provider's API.

This model can then be populated using requests described with traits and implemented by a given service provider. Thus, clients can use the common data model with Rust-native types and idioms but switch in different providers for different data types, markets, or qualities of service.

This library only provides types and traits that can be implemented by a Provider that executes requests for financial data such as price quotes, analyst data, or company information. In the model we use the term request trait to indicate a trait that contains functions that make a request for data and which use the common RequestResult response.

news	Provides structs and traits that retrieve news.
prelude	Re-exports base types required to use request traits.
provider	Provides the trait required by service provider implementations.

registry	A trait to act as a registry of data concerning some classification scheme.
reporting	Provides common types for reporting data.
request	Provides the common Result type and error enum used by request traits.

Macros

assert_is_valid

Short-cut to test whether a Symbol is valid, and if not to return a RequestResult containing the error RequestError::BadSymbolError.
