Enum Shape

pub enum Shape {
    Named,
    Tuple,
    Unit,
    Newtype,
}

Description of how fields in a struct or variant are syntactically laid out.

Variants

Named

A set of named fields, e.g. { field: String }.

Tuple

A list of unnamed fields, e.g. (String, u64).

Unit

No fields, e.g. struct Example;

Newtype

A special case of Tuple with exactly one field, e.g. (String).

Implementations

impl Shape

pub fn description(&self) -> &'static str

Trait Implementations

impl AsShape for Shape

fn as_shape(&self) -> Shape

Get the “shape” of a fields container.

impl Clone for Shape

fn clone(&self) -> Shape

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Shape

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

Formats the value using the given formatter.

impl Display for Shape

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

Formats the value using the given formatter.

impl FromIterator<Shape> for ShapeSet

fn from_iter<T>(iter: T) -> ShapeSet

where T: IntoIterator<Item = Shape>,

Creates a value from an iterator.

impl PartialEq for Shape

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