Struct Validator 

pub struct Validator { /* private fields */ }

Builder for composing multiple validations into a single pass.

Each check captures a (field, ValidationError) pair on failure without short-circuiting, so callers receive every problem at once.

Implementations

impl Validator

pub fn new() -> Self

Create a new validator.

pub fn check<F>(&mut self, field: &str, validation: F) -> &mut Self

where F: FnOnce() -> Result<(), ValidationError>,

Run a validation closure and record any error under field.

pub const fn is_valid(&self) -> bool

Returns true if no check has failed so far.

pub fn errors(&self) -> &[(String, ValidationError)]

Returns a slice of all accumulated errors.

pub fn finish(self) -> Result<(), Vec<(String, ValidationError)>>

Consume the validator and return Ok(()) on success, or the full list of (field, error) pairs otherwise.

Errors

Returns the list of validation errors if any checks failed.

Trait Implementations

impl Debug for Validator

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

Formats the value using the given formatter.

impl Default for Validator

fn default() -> Validator

Returns the “default value” for a type.
