Function write_verifier_to_hierarchy

pub fn write_verifier_to_hierarchy(
    verifier: impl VerifierWriter,
    base_path: impl AsRef<Path>,
    os: Os,
    purpose: Purpose,
    context: Option<Context>,
) -> Result<(), Error>

Writes a verifier to a VOA hierarchy in a directory.

The VerifierWriter implementation writes its on-disk representation to a specific location in a VOA hierarchy in a VOA base path directory based on the os, purpose and optional context identifier.

Errors

Returns an error if VerifierWriter::write_to_hierarchy fails.

Examples

use std::io::Write;

use tempfile::{NamedTempFile, tempdir};
use voa::commands::{load_verifier, write_verifier_to_hierarchy};
