pub struct ValidationErrors(_);

Implementations

impl ValidationErrors

pub fn new() -> ValidationErrors

pub fn has_error(
    result: &Result<(), ValidationErrors>,
    field: &'static str
) -> bool

Returns a boolean indicating whether a validation result includes validation errors for a given field. May be used as a condition for performing nested struct validations on a field in the absence of field-level validation errors.

pub fn merge(
    parent: Result<(), ValidationErrors>,
    field: &'static str,
    child: Result<(), ValidationErrors>
) -> Result<(), ValidationErrors>

Returns the combined outcome of a struct’s validation result along with the nested validation result for one of its fields.

pub fn merge_all(
    parent: Result<(), ValidationErrors>,
    field: &'static str,
    children: Vec<Result<(), ValidationErrors>>
) -> Result<(), ValidationErrors>

Returns the combined outcome of a struct’s validation result along with the nested validation result for one of its fields where that field is a vector of validating structs.

pub fn errors(self) -> HashMap<&'static str, ValidationErrorsKind>

Returns a map of field-level validation errors found for the struct that was validated and any of it’s nested structs that are tagged for validation.

pub fn field_errors(self) -> HashMap<&'static str, Vec<ValidationError>>

Returns a map of only field-level validation errors found for the struct that was validated.

pub fn add(&mut self, field: &'static str, error: ValidationError)

pub fn is_empty(&self) -> bool

impl Error for ValidationErrors

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