Variants

Number(String)

A canonical decimal string.

Blob(String)

A blob reference.

Implementations

impl Scalar

pub fn from_lexical(ty: Type, text: &str) -> Result<Scalar>

Builds a scalar of type ty from its lexical form, checking it (3). For a boolean, text must be true or false (E_CANON_TYPE otherwise).

pub fn from_json(bytes: &[u8]) -> Result<Scalar>

Parses a typed scalar from JSON text (4.1): strict JSON, structure, canonical form.

pub fn ty(&self) -> Type

The scalar’s type.

pub fn lexical(&self) -> &str

The lexical form (true/false for booleans).

pub fn to_value(&self) -> Value

The JSON form {"type": …, "value": …}.

pub fn canonical(&self) -> Vec<u8>

The canonical bytes (6.2) of the typed scalar.

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl Eq for Scalar

impl Hash for Scalar

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 Ord for Scalar

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Scalar

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Scalar

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
