Enum ValueOrArray 

pub enum ValueOrArray<T> {
    Value(T),
    Array(Vec<T>),
}

Available on crate feature eth only.

Union type for representing a single value or a vector of values inside a filter.

Variants

Value(T)

A single value

Array(Vec<T>)

A vector of values

Implementations

impl<T> ValueOrArray<T>

pub const fn as_value(&self) -> Option<&T>

Get the value if present.

pub fn as_array(&self) -> Option<&[T]>

Get the array if present.

pub const fn is_value(&self) -> bool

Check if the enum is a single value.

pub const fn is_array(&self) -> bool

Check if the enum is an array.

Trait Implementations

impl<T> Clone for ValueOrArray<T>

where T: Clone,

fn clone(&self) -> ValueOrArray<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ValueOrArray<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<'a, T> Deserialize<'a> for ValueOrArray<T>

where T: DeserializeOwned,

Available on crate feature serde only.

fn deserialize<D>( deserializer: D, ) -> Result<ValueOrArray<T>, <D as Deserializer<'a>>::Error>

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl From<Address> for ValueOrArray<Address>

fn from(src: Address) -> ValueOrArray<Address>

Converts to this type from the input type.

impl<T> From<ValueOrArray<Option<T>>> for FilterSet<T>

where T: Eq + Hash,

fn from(src: ValueOrArray<Option<T>>) -> FilterSet<T>

Converts to this type from the input type.

impl<T> From<ValueOrArray<T>> for FilterSet<T>

where T: Eq + Hash,

fn from(src: ValueOrArray<T>) -> FilterSet<T>

Converts to this type from the input type.

impl From<Vec<Address>> for ValueOrArray<Address>

fn from(src: Vec<Address>) -> ValueOrArray<Address>

Converts to this type from the input type.

impl From<Vec<FixedBytes<32>>> for ValueOrArray<FixedBytes<32>>

fn from(src: Vec<FixedBytes<32>>) -> ValueOrArray<FixedBytes<32>>

Converts to this type from the input type.

impl<T> Hash for ValueOrArray<T>

where T: Hash,

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<T> PartialEq for ValueOrArray<T>

where T: PartialEq,

fn eq(&self, other: &ValueOrArray<T>) -> 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<T> Serialize for ValueOrArray<T>

where T: Serialize,

Available on crate feature serde only.

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Eq for ValueOrArray<T>

where T: Eq,

impl<T> StructuralPartialEq for ValueOrArray<T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
