Struct EnvValue 

pub struct EnvValue(/* private fields */);

One environment variable’s value, on its way to a sheep.

A newtype for one reason, the same one DogSectionToml exists for: an env value is the single most secret-dense thing a client can send this daemon (a database URL, an API token, a signing key), and a derived Debug on Request would print it in the clear the moment anything logs a request. Every other secret-bearing field on this wire is already protected by its inner type (AppConfig’s own manual Debug prints env: <N vars>), and a bare String here would have been the first field in the enum without that protection.

One direction only. Nothing ever sends one back: Request::SheepConfig answers with the env keys and no values at all.

Self::as_str is the only way out, for the reason DogSectionToml gives: a Deref<Target = str> would hand the type ToString too, and .to_string() would return the value in the clear, defeating the redacted Debug below.

#[serde(transparent)] makes the wire representation identical to a bare String, so this newtype changes nothing about crate::protocol::PROTOCOL_VERSION or the pinned snapshot fixtures.

Implementations

impl EnvValue

pub fn as_str(&self) -> &str

The value.

Trait Implementations

impl Clone for EnvValue

fn clone(&self) -> EnvValue

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EnvValue

Debug prints a length and never the value (IR-41); see the type doc for why. Exact-string-tested below (env_value_debug_does_not_leak) so a future #[derive(Debug)] fails that test instead of silently reopening the leak.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EnvValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EnvValue

impl From<String> for EnvValue

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for EnvValue

fn eq(&self, other: &EnvValue) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for EnvValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
