Enum Prerequisite 

pub enum Prerequisite {
    SequenceCatchUp,
    Reload(Audience),
    Raise {
        audience: Audience,
        version: u32,
    },
}

A fact required before processing can continue.

Variants

SequenceCatchUp

A completed read and apply through the current sequence end.

Reload(Audience)

This audience must reload.

Raise

This audience must be raised to this schema version: a queued write of this device’s at that version has a part in it, and every device would refuse that part until the raise (§18.5).

Fields

audience: Audience

The audience below the write’s version.

version: u32

The version the write is at, this device’s newest breaking migration.

Trait Implementations

impl Clone for Prerequisite

fn clone(&self) -> Prerequisite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Prerequisite

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Prerequisite

fn deserialize<__D>( __deserializer: __D, ) -> Result<Prerequisite, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Prerequisite

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

impl Serialize for Prerequisite

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
