This project provides a set of functions to receive data from the the guru focus website via the GuruFocus API. This project is licensed under Apache 2.0 or MIT license (see files LICENSE-Apache2.0 and LICENSE-MIT).
Please note that you need at least a premium account to use this API. There a couple of
examples demonstrating how to use the API in your own rust projects. To run this example,
you first need to define an environment variable holding the user Token you got from
GuruFocus:
bash
export GURUFOCUS_TOKEN='<your user token>'
The examples can be executed via the command
dummy
cargo test --example <name of example>
Here, <name of example> could be the name of any of the files in the examples folder
without the .rs extension
Please note that running any of the examples increases your API access counter by at least 1.
The GuruFocus API provides all data in JSON format, and the basic API functions currently
will just return these JSON structures as serde_json::Value types without any further
processing. The serde_json::Value types can be deserialized
into more meaningful data structures, as is demonstrated in the gurulist example.
The GuruFocus API returns numbers sometimes as numbers, sometimes as strings. This is dealt
with by introducing a new struct FloatOrString containing a float value, but which can
be read from either a string or float automatically. The drawback is that .val as to be
added to the variable name of a specific data structure. I.e., to access the quoted price
in a variable of type Quote, i.e. q: Quote, the price can be accessed via q.price.val instead
of q.price.
Please note that the library is not yet stable and that the user interface is still subject to change. However, feedback regarding the usability and suggestions for improving the interface are welcome.
