Implementations

impl Shape

pub fn of(v: &Value) -> Shape

Infer shape of a JSON value.

pub fn merge(self, other: Shape) -> Shape

Least-upper-bound merge of two shapes.

pub fn has_field(&self, name: &str) -> bool

True when this shape guarantees the named field exists.

pub fn field(&self, name: &str) -> Option<&Shape>

Shape of self.name if determinable.

pub fn element(&self) -> Option<&Shape>

Shape of self[..] (array element) if this is an array.

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a duplicate 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

Formats the value using the given formatter.

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.

impl Eq for Shape
