Struct Attribute

Source
pub struct Attribute {
    pub name: String,
    pub value: Value,
}
Expand description

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.

Implementations§

Source§

impl Attribute

Source

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

Creates a new Attribute.

Trait Implementations§

Source§

impl Debug for Attribute

Source§

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

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

Source§

impl Display for Attribute

Source§

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

Formats as <name>: <value>.

Source§

impl From<(String, Value)> for Attribute

Source§

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()).

Source§

impl From<Attribute> for (String, Value)

Source§

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).

Source§

impl FromStr for Attribute

Source§

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

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

Source§

type Err = Error<Rule>

The associated error which can be returned from parsing.
Source§

impl PartialEq for Attribute

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 · Source§

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
