Parse from a JSON string

Trait Implementations

impl Clone for DelegationTag

fn clone(&self) -> DelegationTag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DelegationTag

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

Formats the value using the given formatter.

impl Display for DelegationTag

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

Return tag in JSON string format

impl FromStr for DelegationTag

type Err = Error

The associated error which can be returned from parsing.

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

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

impl Hash for DelegationTag

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 DelegationTag

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<DelegationTag> for DelegationTag

fn eq(&self, other: &DelegationTag) -> 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.

impl PartialOrd<DelegationTag> for DelegationTag

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

impl TryFrom<Vec<String, Global>> for DelegationTag

type Error = Error

The type returned in the event of a conversion error.

fn try_from( tag: Vec<String, Global> ) -> Result<DelegationTag, <DelegationTag as TryFrom<Vec<String, Global>>>::Error>

Performs the conversion.
