Enum Signature 

#[non_exhaustive]
#[repr(i32)]
pub enum Signature {
    Ed25519 {
        ed25519: Ed25519Signature,
    },
    MlDsa65 {
        mldsa65: Box<MlDsa65Signature>,
    },
}

Union of a Signature type over the various cryptographic schemes.

The ML-DSA arms of Signature, PublicKey and SecretKey are boxed (heap allocated) in both C++ and Rust, so that Ed25519 signatures and keys, which are most of them, do not each take the size of the largest ML-DSA value in memory.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Signature

pub fn scheme(&self) -> CryptographicScheme

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CollectAuthHandles for Signature

fn collect_auth_handles( &self, _out: &mut AuthHandleBuf, ) -> Result<(), FaultString>

impl ConstMaxSize for Signature

const MAX_SIZE: Option<usize>

Worst-case CXS encoded size in bytes, or None if unbounded.

impl ConstMaxSize for Signature

const MAX_SIZE: Option<usize>

Worst-case TXS encoded size in bytes, or None if unbounded.

impl ContractTypeName for Signature

const NAME: ContractSpecIdView<'static>

The fully qualified id this type is known by in the contract spec.

impl ContractTypeRefSpec for Signature

const INFO: ContractTypeInfo<'static>

The type reference. Transitive type definitions are not carried here; they are retained via the linker-anchor mechanism (__THRUPUT_SPEC_ANCHOR_ROOT) and resolved by spec-tool.

const SIGNED_PREIMAGE: Option<&'static ContractTypeView<'static>> = _

How this type appears as a signed-token preimage (ContractTypeView::SignedToken’s payload): the type itself by default, or None for a type-erased payload (the SDK’s Opaque overrides this).

impl ContractTypeSpec for Signature

const TYPE_DEF: ContractTypeDefView<'static>

The type’s definition (struct, enum, or union) as a const view.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Default for Signature

fn default() -> Signature

Returns the “default value” for a type.

impl EncodesAs<Signature> for Signature

impl Eq for Signature

impl Hash for Signature

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

where __H: Hasher,

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 JsonSchema for Signature

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

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 inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Mintable for Signature

fn mint_into_parent(preimage: Signature, _children: &mut ChildNodeBuf) -> Self

impl MintableType for Signature

type Preimage = Signature

impl Ord for Signature

fn cmp(&self, other: &Signature) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Signature

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Signature

fn partial_cmp(&self, other: &Signature) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'_r> ReadXDR<'_r> for Signature

fn read_xdr<R>(r: &mut R) -> Result<Signature, ReadError>

where R: Reader<'_r>,

Reads an XDR value from the reader.

fn read_xdr_in_place<'s, R>( r: &mut R, slot: Slot<'s, Self>, ) -> Result<Init<'s, Self>, ReadError>

where R: Reader<'r>,

Reads an XDR value directly into slot, without first building it on the stack.

impl ReceiveAuthHandles for Signature

fn receive_auth_handles( &mut self, _handles: &mut impl Iterator<Item = u32>, ) -> Result<(), AuthTokenError>

impl StructuralPartialEq for Signature

impl WriteXDR for Signature
