Struct JsonForm 

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

Accumulates field-extraction failures from a JsonObject into a single ValidationError.

Create one with new, pull each field with str_field, then call finish to get Ok(()) or every collected Violation at once.

Implementations

impl<'a> JsonForm<'a>

pub fn new(object: &'a JsonObject) -> Self

Starts a form over object with no recorded violations.

pub fn str_field<T>(&mut self, field: &'static str) -> Option<T>

where T: TryFrom<&'a str, Error = PrimitiveError>,

Extracts field as a string-backed primitive T.

On success returns Some(value). On failure records a Violation named field (with a fixed summary message) and returns None, so validation continues and every bad field is reported by finish.

pub fn is_valid(&self) -> bool

Returns true if no violations have been recorded yet.

pub fn errors(&self) -> &ValidationError

Borrows the violations recorded so far.

pub fn finish(self) -> ValidateResult

Consumes the form: Ok(()) if every field validated, otherwise Err with all collected violations.
