Struct sdlang::Attribute

pub struct Attribute {
    pub name: String,
    pub value: Value,
}

A value with an associated name, forming a single attribute.

Multiple attributes may be placed on tags.

Conversion functions are providing for parsing and for converting to and from a (String, Value) tuple (useful for collecting a set of attributes into a hash map).

Fields

name: String

The name of the attribute.

value: Value

The associated value.

Methods

impl Attribute

pub fn new(name: String, value: Value) -> Self

Creates a new Attribute.

Trait Implementations

impl PartialEq<Attribute> for Attribute

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

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

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

This method tests for !=.

impl From<(String, Value)> for Attribute

fn from((k, v): (String, Value)) -> Self

Converts from a key-value tuple.

Useful when converting from an iterator of key-value pairs (which may originate from HashMap::iter()).

impl From<Attribute> for (String, Value)

fn from(attr: Attribute) -> Self

Converts into a key-value tuple.

Useful when converting into an iterator of key-value pairs (which may be collected into a HashMap).

impl Display for Attribute

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

Formats as <name>: <value>.

impl Debug for Attribute

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

Formats the same way as fmt::Display. Useful for non-excessive debug output.

impl FromStr for Attribute

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses the text for an Attribute, returning a parse error on failure.
