Struct Credentials 

#[non_exhaustive]
pub struct Credentials {
    pub pid: Option<ProcessId>,
    pub same_user: bool,
    pub user_evidence: UserEvidence,
}

What the operating system reports about the other end of one connection.

Read them while the connection is open and before dispatching anything. Later fields, such as a code-signature result, will be added without a breaking change; construct them with Credentials::new.

Equality compares pid and same_user only. user_evidence says where same_user came from; compare it explicitly when it matters.

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.

pid: Option<ProcessId>

Kernel-reported PID of the peer, or None when the platform reports none.

same_user: bool

Whether the peer runs as this process’s OS user.

user_evidence: UserEvidence

Where same_user came from.

Implementations

impl Credentials

pub const fn new(pid: Option<ProcessId>, same_user: bool) -> Self

Credentials from an OS query, or for a consumer’s own tests and sources. The user check is taken to come from the connection; see Self::with_user_evidence.

pub const fn with_user_evidence(self, evidence: UserEvidence) -> Self

The same credentials, with same_user coming from evidence.
