Enum SigDataType

pub enum SigDataType {
    Exact(DataType),
    Any,
    AnyArray,
    AnyStruct,
    AnyMap,
}

An extended data type that can be used to declare a function’s argument or result type.

Variants

Exact(DataType)

Exact data type

Any

Accepts any data type

AnyArray

Accepts any array data type

AnyStruct

Accepts any struct data type

AnyMap

TODO: not all type can be used as a map key.

Implementations

impl SigDataType

pub fn matches(&self, dt: &DataType) -> bool

Returns true if the data type matches.

pub fn as_exact(&self) -> &DataType

Returns the exact data type.

pub fn is_exact(&self) -> bool

Returns true if the data type is exact.

Trait Implementations

impl Clone for SigDataType

fn clone(&self) -> SigDataType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SigDataType

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

Formats the value using the given formatter.

impl Display for SigDataType

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

Formats the value using the given formatter.

impl From<DataType> for SigDataType

fn from(dt: DataType) -> Self

Converts to this type from the input type.

impl Hash for SigDataType

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 Ord for SigDataType

fn cmp(&self, other: &SigDataType) -> 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.

impl PartialEq for SigDataType

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SigDataType

fn partial_cmp(&self, other: &SigDataType) -> 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.
