    Name(FieldName),
    ElementType,
}

Selects a nested type within either a struct or a list.

Implementations

impl Field

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

Retrieve a field name if it has one

pub fn is_named(&self) -> bool

Returns true if the field is defined by Name

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl Display for Field

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

Formats the value using the given formatter.

impl From<&str> for Field

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Arc<str>> for Field

fn from(value: Arc<str>) -> Self

Converts to this type from the input type.

impl From<Field> for FieldPath

fn from(value: Field) -> Self

Converts to this type from the input type.

impl FromIterator<Field> for FieldPath

fn from_iter<T: IntoIterator<Item = Field>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for Field

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Field

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