Help: No matching package

[phodina]

Greetings,
I want to package a Rust crate `calculate` available on Gitlab. So I created 
the package description and defined also another one `decimal`.

Package `rust-decimal` build correctly.
However, when I want to build `calculate` package it complains that the crate 
is not available.

starting phase `build'
error: no matching package named `decimal` found

As the crate is not available on crates.io I had to substitute the dependency 
in Cargo.toml.

The crate is listed in #:cargo-inputs. I'm wondering about what I'm doing wrong?

Source code is listed below.

Kind regards
Petr
