Struct EnvVarOptions 

#[non_exhaustive]
pub struct EnvVarOptions {
    pub prefix: String,
}

Options for rendering environment variable names.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

prefix: String

Prefix prepended to generated env var names, e.g. APP_.
