Implementations

impl ParamAnnotation

pub fn parse(name: &str, value: Option<&str>) -> Self

Trait Implementations

impl Clone for ParamAnnotation

fn clone(&self) -> ParamAnnotation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamAnnotation

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

Formats the value using the given formatter.

impl PartialEq for ParamAnnotation

fn eq(&self, other: &ParamAnnotation) -> 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 ParamAnnotation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ParamAnnotation

impl StructuralPartialEq for ParamAnnotation
