Enum FormParseError

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

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.

Trait Implementations

impl<'f> Clone for FormParseError<'f>

fn clone(&self) -> FormParseError<'f>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'f> Debug for FormParseError<'f>

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

Formats the value using the given formatter.

impl<'f> Hash for FormParseError<'f>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'f> PartialEq for FormParseError<'f>

fn eq(&self, other: &FormParseError<'f>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
