Struct Bytes

pub struct Bytes<Request = ()>(pub Request);

The Bytes strategy represents raw state bytes. It is both an inspect and update strategy.

• As the inspect strategy, it returns Vec<u8>.
• As the update strategy, it accepts Option<&[u8]>, where None means data removal.

By default, the Bytes identifies a byte blob associated with the asset (the only one blob). However, a user can define several variants of this strategy by supplying the Request type. The Request type can also contain additional data (like a byte key) to identify a certain byte data. For instance, there can be several named byte attributes. In that case, the Request might be something like Attribute(/* name: */ String).

Trait Implementations

impl Default for Bytes<()>

fn default() -> Self

Returns the “default value” for a type.

impl<Request> InspectStrategy for Bytes<Request>

type Value = Vec<u8>

The value representing the asset’s state related to this InspectStrategy.

impl<Request> UpdateStrategy for Bytes<Request>

type UpdateValue<'u> = Option<&'u [u8]>

The value to update the asset’s state. Usually, it should be related to the corresponding InspectStrategy::Value.

type Success = ()

This type represents a successful asset state update. It will be in the Result type of the Update::update function.
