Enum HostIdentityReason

pub enum HostIdentityReason {
    NoExpectation,
    UidMismatch {
        host: Option<u32>,
        client: u32,
    },
    PidUnavailable,

Why a host was refused. Always the host’s identity, never a connection problem.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoExpectation

The expectation names no executable, so no host can match. Fails closed.

UidMismatch

The host runs as another user than this client.

Fields

host: Option<u32>

client: u32

PidUnavailable

The OS did not report the host’s process id (a BSD, or a pid namespace that hides it).

Unreadable(String)

The kernel would not describe the host process (permission, or the call failed).

ExecutableMismatch

The host’s executable is not one of the expected executables.

HostChanged(String)

The process behind the socket exited or changed while it was being identified, so the pid could not be proven to name one process throughout.

Refused(String)

The executable matched but the caller’s extra verification refused the host.

Unverified

Identifying the host is not implemented for this platform. Fails closed: it never means “assume it is the right one”.

Fields

platform: &'static str

detail: &'static str

Query(String)

The OS could not answer the peer-credential query.
