Struct linera_base::data_types::Blob

pub struct Blob { /* private fields */ }

A blob of binary data, with its hash.

Implementations

impl Blob

pub fn new(content: BlobContent) -> Self

Computes the hash and returns the hashed blob for the given content.

pub fn new_with_id_unchecked( blob_id: BlobId, bytes: impl Into<Box<[u8]>>, ) -> Self

Creates a blob without checking that the hash actually matches the content.

pub fn new_data(bytes: impl Into<Box<[u8]>>) -> Self

Creates a new data Blob from the provided bytes.

pub fn new_contract_bytecode(compressed_bytecode: CompressedBytecode) -> Self

Creates a new contract bytecode BlobContent from the provided bytes.

pub fn new_service_bytecode(compressed_bytecode: CompressedBytecode) -> Self

Creates a new service bytecode BlobContent from the provided bytes.

pub fn id(&self) -> BlobId

A content-addressed blob ID i.e. the hash of the Blob.

pub fn content(&self) -> &BlobContent

Returns a reference to the inner BlobContent, without the hash.

pub fn into_content(self) -> BlobContent

Moves ownership of the blob of binary data

pub fn bytes(&self) -> &[u8]

Gets a reference to the inner blob’s bytes.

pub fn into_bytes(self) -> Box<[u8]>

Gets the inner blob’s bytes.

pub async fn load_data_blob_from_file(path: impl AsRef<Path>) -> Result<Self>

Loads data blob from a file.

Trait Implementations

impl Clone for Blob

fn clone(&self) -> Blob

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blob

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Blob

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

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl From<Blob> for BlobContent

fn from(blob: Blob) -> BlobContent

Converts to this type from the input type.

impl Hash for Blob

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl InputType for Blob

type RawValueType = Blob

The raw type used for validator.

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.

fn parse(value: Option<Value>) -> InputValueResult<Self>

Parse from Value. None represents undefined.

fn to_value(&self) -> Value

Convert to a Value for introspection.

fn as_raw_value(&self) -> Option<&Self::RawValueType>

Returns a reference to the raw value.

fn qualified_type_name() -> String

Qualified typename.

impl OutputType for Blob

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, _: &ContextSelectionSet<'_>, _field: &Positioned<Field>, ) -> ServerResult<Value>

Resolve an output value to async_graphql::Value.

fn qualified_type_name() -> String

Qualified typename.

fn introspection_type_name(&self) -> Cow<'static, str>

Introspection type name

impl PartialEq for Blob

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

impl ScalarType for Blob

fn parse(value: Value) -> InputValueResult<Self>

Parse a scalar value.

fn to_value(&self) -> Value

Convert the scalar to Value.

fn is_valid(_value: &ConstValue) -> bool

Checks for a valid scalar value.

impl Serialize for Blob

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Blob

impl StructuralPartialEq for Blob
