Enum FieldError 

pub enum FieldError {
    Required(String),
    Invalid(String),
    Validation(String),
}

Available on crate feature forms and non-WebAssembly only.

Error type returned when field validation fails.

Variants

Required(String)

The field is required but no value was provided.

Invalid(String)

The field value has an invalid format or type.

Validation(String)

The field value failed a validation constraint (e.g., length, range).

Implementations

impl FieldError

pub fn required(custom_msg: Option<&str>) -> FieldError

Creates a required field error

Examples

use reinhardt_forms::FieldError;

let error = FieldError::required(None);
assert_eq!(error.to_string(), "This field is required.");

let custom_error = FieldError::required(Some("Name is mandatory"));
assert_eq!(custom_error.to_string(), "Name is mandatory");

pub fn invalid(custom_msg: Option<&str>, default_msg: &str) -> FieldError

Creates an invalid field error

Examples

use reinhardt_forms::FieldError;

let error = FieldError::invalid(None, "Invalid input format");
assert_eq!(error.to_string(), "Invalid input format");

let custom_error = FieldError::invalid(Some("Must be a number"), "Invalid");
assert_eq!(custom_error.to_string(), "Must be a number");

pub fn validation(custom_msg: Option<&str>, default_msg: &str) -> FieldError

Creates a validation field error

Examples

use reinhardt_forms::FieldError;

let error = FieldError::validation(None, "Value out of range");
assert_eq!(error.to_string(), "Value out of range");

let custom_error = FieldError::validation(Some("Too long"), "Length exceeded");
assert_eq!(custom_error.to_string(), "Too long");

Trait Implementations

impl Debug for FieldError

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

Formats the value using the given formatter.

impl Display for FieldError

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

Formats the value using the given formatter.

impl Error for FieldError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
