Struct ac_node_api::decoder::Value

pub struct Value<T = ()> {
    pub value: ValueDef<T>,
    pub context: T,
}

Value holds a representation of some value that has been decoded, as well as some arbitrary context.

Not all SCALE encoded types have an similar-named value; for instance, the values corresponding to sequence, array and composite types can all be represented with Composite. Only enough information is preserved here to to be able to encode and decode SCALE bytes with a known type to and from Values losslessly.

Fields

value: ValueDef<T>

The shape and associated data for this Value

context: T

Some additional arbitrary context that can be associated with a value.

Trait Implementations

impl<T: Clone> Clone for Value<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Value<T>

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

Formats the value using the given formatter.

impl From<BitVec<u8, Lsb0>> for Value<()>

fn from(val: BitSequence) -> Self

Converts to this type from the input type.

impl From<String> for Value<()>

fn from(val: String) -> Self

Converts to this type from the input type.

impl<K: Into<String>, V: Into<Value<()>>> From<Vec<(K, V), Global>> for Value<()>

fn from(vals: Vec<(K, V)>) -> Self

Converts to this type from the input type.

impl<V: Into<Value<()>>> From<Vec<V, Global>> for Value<()>

fn from(vals: Vec<V>) -> Self

Converts to this type from the input type.

impl From<bool> for Value<()>

fn from(val: bool) -> Self

Converts to this type from the input type.

impl From<char> for Value<()>

fn from(val: char) -> Self

Converts to this type from the input type.

impl From<i128> for Value<()>

fn from(val: i128) -> Self

impl<T: PartialEq> PartialEq<Value<T>> for Value<T>

fn eq(&self, other: &Value<T>) -> 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.
