Struct Validator 

pub struct Validator<'a> { /* private fields */ }

Fluent per-field validator. See module docs.

Implementations

impl<'a> Validator<'a>

pub fn new(input: &'a PluginInput) -> Self

pub fn require_str(&mut self, key: &str) -> &mut Self

Require a present, non-empty string.

pub fn require_enum(&mut self, key: &str, allowed: &[&str]) -> &mut Self

Require a string field whose value is one of allowed.

pub fn require_gtin(&mut self, key: &str) -> &mut Self

Require a 14-digit GS1 GTIN string with a valid check digit.

pub fn require_country(&mut self, key: &str) -> &mut Self

Require a recognized ISO 3166-1 alpha-2 country code.

pub fn require_positive(&mut self, key: &str) -> &mut Self

Require a present, finite number greater than 0.

pub fn require_non_negative(&mut self, key: &str) -> &mut Self

Require a present, finite number greater than or equal to 0.

pub fn require_pct(&mut self, key: &str) -> &mut Self

Require a present, finite number in [0, 100].

pub fn require_positive_int(&mut self, key: &str) -> &mut Self

Require a present non-negative integer that is at least 1.

pub fn require_bool(&mut self, key: &str) -> &mut Self

Require a present boolean.

pub fn require_non_empty_array(&mut self, key: &str) -> &mut Self

Require a present, non-empty array.

pub fn optional_pct(&mut self, key: &str) -> &mut Self

If present (and non-null), the value must be a finite number in [0, 100].

pub fn optional_range(&mut self, key: &str, min: f64, max: f64) -> &mut Self

If present (and non-null), the value must be a finite number in [min, max].

For a field that is optional (its absence is meaningful) but must be bounded when supplied — e.g. a 0–10 repairability score that gates a verdict only when present.

pub fn optional_non_negative(&mut self, key: &str) -> &mut Self

If present (and non-null), the value must be a finite number ≥ 0.

pub fn finish(&mut self) -> Result<(), PluginError>

Finish validation, returning every collected error at once.
