Enum SessionProvider 

pub enum SessionProvider {
    Legacy,
    OpenTacenta,
}

Which implementation established the sessions in a state blob.

A session cannot be carried between them: the two derive keys under different labels, so one provider’s session is unreadable by the other. A client restoring state has to know which it is holding before it can decide whether to continue the session or drop it and establish again. That is what this records, and it is step 2 of the migration in decision record 0056.

It lives in the state envelope rather than inside a provider’s own session blob, because the question it answers is which blob to hand to which provider.

Variants

Legacy

The provider used before this field existed; the default a pre-tag blob restores as.

OpenTacenta

open-tacenta, behind the open-provider feature.

Implementations

impl SessionProvider

pub fn to_byte(self) -> u8

The byte this provider is written as in the state envelope.

Trait Implementations

impl Clone for SessionProvider

fn clone(&self) -> SessionProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SessionProvider

impl Debug for SessionProvider

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

Formats the value using the given formatter.

impl Eq for SessionProvider

impl PartialEq for SessionProvider

fn eq(&self, other: &SessionProvider) -> 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.
