Implementations

impl TypeTag

pub fn to_canonical_string(&self, with_prefix: bool) -> String

Return a canonical string representation of the type. All types are represented using their source syntax: “u8”, “u64”, “u128”, “bool”, “address”, “vector”, “signer” for ground types. Struct types are represented as fully qualified type names; e.g. 00000000000000000000000000000001::string::String or 0000000000000000000000000000000a::module_name1::type_name1<0000000000000000000000000000000a::module_name2::type_name2<u64>> With or without the prefix 0x depending on the with_prefix flag. Addresses are hex-encoded lowercase values of length ADDRESS_LENGTH (16, 20, or 32 depending on the Move platform) Note: this function is guaranteed to be stable, and this is suitable for use inside Move native functions or the VM. By contrast, the Display implementation is subject to change and should not be used inside stable code.

pub fn to_canonical_display(&self, with_prefix: bool) -> impl Display

Return the canonical string representation of the TypeTag conditionally with prefix 0x

pub fn abstract_size_for_gas_metering(&self) -> GasQuantity<AbstractMemoryUnit>

Return the abstract size we use for gas metering This size might be imperfect but should be consistent across platforms TODO (ade): use macro to enfornce determinism

Trait Implementations

impl Arbitrary for TypeTag

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<TypeTag>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _args: <TypeTag as Arbitrary>::Parameters ) -> <TypeTag as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for TypeTag

fn clone(&self) -> TypeTag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeTag

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TypeTag

fn deserialize<__D>( __deserializer: __D ) -> Result<TypeTag, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'de> DeserializeAs<'de, TypeTag> for SuiTypeTag

fn deserialize_as<D>(deserializer: D) -> Result<TypeTag, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TypeTag

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

Formats the value using the given formatter.

impl From<&MoveTypeLayout> for TypeTag

fn from(val: &MoveTypeLayout) -> TypeTag

Converts to this type from the input type.

impl From<MoveObjectType> for TypeTag

fn from(o: MoveObjectType) -> TypeTag

Converts to this type from the input type.

impl From<StructTag> for TypeTag

fn from(t: StructTag) -> TypeTag

Converts to this type from the input type.

impl FromStr for TypeTag

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<TypeTag, <TypeTag as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for TypeTag

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 Ord for TypeTag

fn cmp(&self, other: &TypeTag) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TypeTag

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

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

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

impl PartialOrd for TypeTag

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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