Struct ValidationError 

pub struct ValidationError {
    pub kind: ValidationErrorKind,
    pub path: String,
    pub field: String,
    pub message: String,
    pub frame: Option<u32>,
}

A property-level diagnostic, independent of fonts, GPU initialization and I/O.

Fields

kind: ValidationErrorKind

Category suitable for programmatic handling.

path: String

Structural path, such as layers[2].mask.group.layers[0].

field: String

The invalid property or exhausted allowance.

message: String

The specific constraint that failed.

frame: Option<u32>

The requested frame index, when supplied by composition preflight or rendering.

Implementations

impl ValidationError

pub fn new( kind: ValidationErrorKind, path: impl Into<String>, field: impl Into<String>, message: impl Into<String>, ) -> Self

Creates a property diagnostic without binding it to an output frame.

pub fn invalid( path: impl Into<String>, field: impl Into<String>, message: impl Into<String>, ) -> Self

Creates an invalid-value diagnostic for a rejected property.

pub fn limit( path: impl Into<String>, field: impl Into<String>, message: impl Into<String>, ) -> Self

Creates a structural, work or storage allowance diagnostic.

pub fn unsupported( path: impl Into<String>, field: impl Into<String>, message: impl Into<String>, ) -> Self

Creates a diagnostic for input that is valid but not supported.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Eq for ValidationError

impl Error for ValidationError

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.

impl From<ValidationError> for Error

fn from(error: ValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for ValidationError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
