Struct linera_base::hashed::Hashed

pub struct Hashed<T> { /* private fields */ }

Wrapper type around hashed instance of T type.

Implementations

impl<T> Hashed<T>

pub fn unchecked_new(value: T, hash: CryptoHash) -> Self

Creates an instance of Hashed with the given hash value.

Note on usage: This method is unsafe because it allows the caller to create a Hashed with a hash that doesn’t match the value. This is necessary for the rewrite state when signers sign over old Certificate type.

pub fn new<'de>(value: T) -> Self

where T: BcsHashable<'de>,

Creates an instance of Hashed with the given value.

Note: Contrary to its unchecked_new counterpart, this method is safe because it calculates the hash from the value.

pub fn hash(&self) -> CryptoHash

Returns the hash.

pub fn inner(&self) -> &T

Returns a reference to the value, without the hash.

pub fn into_inner(self) -> T

Consumes the hashed value and returns the value without the hash.

Trait Implementations

impl<T: Clone> Clone for Hashed<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: OutputType + Clone> ContainerType for Hashed<T>

async fn resolve_field(&self, ctx: &Context<'_>) -> ServerResult<Option<Value>>

Resolves a field value and outputs it as a json value async_graphql::Value.

async fn find_entity( &self, ctx: &Context<'_>, params: &Value, ) -> ServerResult<Option<Value>>

Find the GraphQL entity with the given name from the parameter.

fn collect_all_fields<'a>( &'a self, ctx: &ContextBase<'a, &'a Positioned<SelectionSet>>, fields: &mut Fields<'a>, ) -> Result<(), ServerError>

where Self: Send + Sync,

Collect all the fields of the container that are queried in the selection set.

impl<T> Debug for Hashed<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<'de, T: BcsHashable<'de>> Deserialize<'de> for Hashed<T>

fn deserialize<D>(deserializer: D) -> Result<Hashed<T>, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: OutputType + Clone> OutputType for Hashed<T>

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

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

async fn resolve( &self, ctx: &ContextSelectionSet<'_>, _field: &Positioned<Field>, ) -> ServerResult<Value>

Resolve an output value to async_graphql::Value.

fn qualified_type_name() -> String

impl<T> PartialEq for Hashed<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
