Enum NfsTransportSecurity 

pub enum NfsTransportSecurity {
    None,
    Tls,
    Opportunistic,
}

NFS transport security mode from xprtsec= mount option (RFC 9289).

Orthogonal to NfsSecurity (the sec= authentication flavor). TLS provides transport-layer encryption; RPCSEC_GSS provides user authentication. They can be combined: sec=krb5,xprtsec=tls gives Kerberos auth over TLS encryption.

Variants

None

No TLS – cleartext TCP transport (default, backward compatible).

Tls

RPC-over-TLS via RFC 9289 STARTTLS upgrade. Mandatory: fail if server doesn’t support TLS. Detected from xprtsec=tls or xprtsec=mtls.

Opportunistic

Try RPC-over-TLS, fall back to cleartext if server rejects STARTTLS. Useful for mixed environments during TLS rollout.

Trait Implementations

impl Clone for NfsTransportSecurity

fn clone(&self) -> NfsTransportSecurity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NfsTransportSecurity

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

Formats the value using the given formatter.

impl Default for NfsTransportSecurity

fn default() -> NfsTransportSecurity

Returns the “default value” for a type.

impl PartialEq for NfsTransportSecurity

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
