Struct Compatibilities 

#[non_exhaustive]
pub struct Compatibilities {
    pub tls12: Compatibility,
    pub tls13: Compatibility,
}

The current Linux kernel’s kTLS cipher suites compatibility.

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.

tls12: Compatibility

TLS 1.2 cipher suite compatibility.

tls13: Compatibility

TLS 1.3 cipher suite compatibility.

Implementations

impl Compatibilities

pub fn probe() -> Result<Option<Self>>

Probes the current Linux kernel for kTLS cipher suites compatibility.

Returns Ok(None) if the running kernel does not support kTLS, i.e., tls module is not available. If the kernel is modern enough (at least 5.4), it should support kTLS but might not have tls module loaded.

The caller can cache the successful result of this method, while the supporting cipher suites are unlikely to change during the program’s lifetime. Note that the attempt to configure TLS ULP still might fail due to kTLS being unsupported, while the tls module can be loaded / unloaded at runtime.

The caller should check the returned Compatibilitys with Compatibility::is_unsupported to see whether the desired TLS version is totally unsupported.

Errors

io::Error.
