Enum Callback

pub enum Callback {
    Execute(Result<ExecutionResponse, String>),
    FatalError(String),
}

Variants

Execute(Result<ExecutionResponse, String>)

Result of executing the requested messages, or an error.

14/04/23: if a submessage errors the reply handler can see codespace: wasm, code: 5, but not the actual error. as a result, we can’t return good errors for Execution and this error string will only tell you the error’s codespace. for example, an out-of-gas error is code 11 and looks like codespace: sdk, code: 11.

FatalError(String)

An error occured that could not be recovered from. The only known way that this can occur is message handling running out of gas, in which case the error will be codespace: sdk, code: 11.

This error is not named because it could also occur due to a panic or unhandled error during message processing. We don’t expect this to happen and have carefully written the code to avoid it.

Trait Implementations

impl Clone for Callback

fn clone(&self) -> Callback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Callback

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Callback

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Callback

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for Callback

fn eq(&self, other: &Callback) -> 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 Callback

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
