Trait Implementations

impl<T> BorshSchema for PromiseOrValue<T> where
    T: BorshSchema, 

fn add_definitions_recursively(
    definitions: &mut HashMap<Declaration, Definition>
)

Recursively, using DFS, add type definitions required for this type. For primitive types this is an empty map. Type definition explains how to serialize/deserialize a type.

fn declaration() -> Declaration

Get the name of the type without brackets.

fn add_definition(
    declaration: String,
    definition: Definition,
    definitions: &mut HashMap<String, Definition, RandomState>
)

Helper method to add a single type definition to the map.

fn schema_container() -> BorshSchemaContainer

impl<T: BorshSerialize> BorshSerialize for PromiseOrValue<T>

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it's worth handling it as a special case to improve performance. It's a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl<T> From<Promise> for PromiseOrValue<T>

fn from(promise: Promise) -> Self

Performs the conversion.

impl<T: Serialize> Serialize for PromiseOrValue<T>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.
