Struct edn_format::Keyword

pub struct Keyword { /* fields omitted */ }

A keyword, as described in EDN data model, is identifier which should “designate itself”.

Because its contents are interned, cloning and comparisons should be relatively cheap operations and construction relatively expensive.

Implementations

impl Keyword

pub fn namespace(&self) -> Option<&str>

The namespace of the keyword, if there is one.

pub fn name(&self) -> &str

The name of the keyword.

pub fn from_name(name: &str) -> Keyword

Construct a keyword from a name.

There are no safeguards in place for ensuring that the name given would be valid EDN.

pub fn from_namespace_and_name(namespace: &str, name: &str) -> Keyword

Construct a keyword from a namespace and a name.

There are no safeguards in place for ensuring that either the namespace or the name given would be valid EDN.

Trait Implementations

impl Clone for Keyword

fn clone(&self) -> Keyword

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Keyword

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

Formats the value using the given formatter.

impl Display for Keyword

If the namespace and name of the symbol follow the proper rules, displaying a keyword should give valid EDN.

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

Formats the value using the given formatter.

impl Hash for Keyword

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for Keyword

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Keyword> for Keyword

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

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

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

This method tests for !=.

impl PartialOrd<Keyword> for Keyword

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