Enum MetadataValue 

pub enum MetadataValue {
    Bool(bool),
    Integer(i64),
    Float(f64),
    String(String),
}

A metadata value with type coercion matching the JS parser behavior.

Variants

Bool(bool)

Integer(i64)

Float(f64)

String(String)

Implementations

impl MetadataValue

pub fn to_frontmatter_string(&self) -> String

Serialize to the string form used in YAML frontmatter.

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

Get as a string reference (only for String variant).

pub fn is_falsy(&self) -> bool

Check if the value is falsy (for omit-when-falsy serialization).

Trait Implementations

impl Clone for MetadataValue

fn clone(&self) -> MetadataValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetadataValue

fn deserialize<__D>( __deserializer: __D, ) -> Result<MetadataValue, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MetadataValue

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

Formats the value using the given formatter.

impl PartialEq for MetadataValue

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for MetadataValue

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
