Struct Number 

pub struct Number { /* private fields */ }

(number feature) Accepts either an integer or a float, without converting between them.

Use this when a value may legitimately be whole or fractional and you want to keep its original type. Optional inclusive bounds and sign constraints compare the value numerically but never rewrite it.

Implementations

impl Number

pub fn with_meta(self, meta: Meta) -> Self

Attach human-facing metadata (name, description, examples, default, output conversion).

pub fn new() -> Self

pub fn min(self, min: f64) -> Self

pub fn max(self, max: f64) -> Self

pub fn range(self, start: f64, end: f64) -> Self

pub fn positive(self) -> Self

Require the value to be strictly greater than zero.

pub fn non_negative(self) -> Self

Require the value to be greater than or equal to zero.

pub fn negative(self) -> Self

Require the value to be strictly less than zero.

pub fn non_positive(self) -> Self

Require the value to be less than or equal to zero.

Trait Implementations

impl Clone for Number

fn clone(&self) -> Number

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl Default for Number

fn default() -> Number

Returns the “default value” for a type.

impl Validator for Number

fn meta(&self) -> &Meta

This validator’s human-facing metadata.

fn meta_mut(&mut self) -> &mut Meta

Mutable access to this validator’s metadata (backs the WithMeta builder setters).

fn check(&self, value: &mut Value) -> Result<(), Error>

The validation rule: check (and coerce) value in place.

fn validate(&self, value: &mut Value) -> Result<(), Error>

Run check; on error attach this validator’s Meta (innermost wins); on success apply the output conversion in meta().convert, if any.
