Struct SecretValue 

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

A health-check header value held in memory only.

There is no Clone, Serialize, Deserialize or Display, and Debug prints a placeholder. The single way to read the bytes is SecretValue::expose_secret_bytes; call it only for the fingerprint HMAC and for the controlled in-memory IPC and wire builders.

Implementations

impl SecretValue

pub fn take_from_ingress( message: &mut HealthCheckHeaderValue, ) -> Result<Self, SecretValueError>

Move the value out of a generated ingress message.

The allocation moves with std::mem::take, so no copy is made and the generated field is left empty whether or not the value is accepted. The value must be UTF-8 and meet the per-value rules every health-check header meets (no forbidden control byte, no leading or trailing SP or HTAB); the name is the caller’s to validate.

pub fn expose_secret_bytes(&self) -> &[u8]

The clear bytes. The name is the warning: the only legitimate callers are the fingerprint HMAC and the controlled in-memory IPC and wire builders that carry the value onward.

Trait Implementations

impl Debug for SecretValue

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

Formats the value using the given formatter.
