Struct FieldRef 

pub struct FieldRef<'a, 'b> {
    pub metadata: &'a FieldMetadata<'b>,
    pub value: &'a dyn FieldValue,
}

Fields

metadata: &'a FieldMetadata<'b>

A reference to field’s metadata.

value: &'a dyn FieldValue

An reference to the actual value of the property. This is “non-mangled” reference, which means that while field/fields/field_mut/fields_mut might return a reference to other value, than the actual field, the value is guaranteed to be a reference to the real value.

Implementations

impl FieldRef<'_, '_>

pub fn cast_value<T: 'static>(&self) -> Result<&T, CastError>

Tries to cast a value to a given type.

Trait Implementations

impl Debug for FieldRef<'_, '_>

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

Formats the value using the given formatter.

impl<'b> Deref for FieldRef<'_, 'b>

type Target = FieldMetadata<'b>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl PartialEq for FieldRef<'_, '_>

fn eq(&self, other: &Self) -> 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.
