Struct smart_config::de::FromSecretString

pub struct FromSecretString;

Deserializer for secret strings (any type convertible from SecretString, including SecretString itself). Will set the corresponding flag for ParamMetadata, making raw param value hidden in the debug output etc.

Examples

use secrecy::ExposeSecret;

#[derive(DescribeConfig, DeserializeConfig)]
struct TestConfig {
    secret: secrecy::SecretString,
}

let input = smart_config::config!("secret": "correct horse battery staple");
let config: TestConfig = testing::test(input)?;
assert_eq!(config.secret.expose_secret(), "correct horse battery staple");
