envsubst

A simple Rust library for variables substitution.

This library provide helper functions for string manipulation, taking values from a context environment map and substituting all matching placeholders.

Its name and logic is similar to the [envsubst] GNU utility, but this only supports braces-delimited variables (i.e. ${foo}) and takes replacement values from an explicit map of variables.
