pub enum FormParseError<'f> {
    BadValue(&'f RawStr, &'f RawStr),
    Unknown(&'f RawStr, &'f RawStr),
    Missing(&'f RawStr),
}
Expand description

Error returned by the FromForm derive on form parsing errors.

If multiple errors occur while parsing a form, the first error in the following precedence, from highest to lowest, is returned:

  • BadValue or Unknown in incoming form string field order
  • Missing in lexical field order

Variants§

§

BadValue(&'f RawStr, &'f RawStr)

The field named .0 with value .1 failed to parse or validate.

§

Unknown(&'f RawStr, &'f RawStr)

The parse was strict and the field named .0 with value .1 appeared in the incoming form string but was unexpected.

This error cannot occur when parsing is lenient.

§

Missing(&'f RawStr)

The field named .0 was expected but is missing in the incoming form.
