Struct Integer 

pub struct Integer { /* private fields */ }

(integer feature) Accepts an integer, with optional inclusive bounds and lenient coercion.

Coercion:

• an integer stays as-is;
• a string is parsed as an integer, or as an integral float (e.g. "3.0");
• a float with no fractional part (e.g. 3.0) becomes an integer.

Implementations

impl Integer

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: isize) -> Self

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

pub fn range(self, start: isize, end: isize) -> 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 Integer

fn clone(&self) -> Integer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Integer

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

Formats the value using the given formatter.

impl Default for Integer

fn default() -> Integer

Returns the “default value” for a type.

impl Validator for Integer

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.
