Struct ValueError 

pub struct ValueError {
    pub kind: ValueErrorKind,
    pub source_path: Vec<PathSegment>,
    pub dest_path: Vec<PathSegment>,
    pub target_shape: Option<&'static Shape>,
    pub source_value: Option<Value>,
}

Error type for Value deserialization.

Fields

kind: ValueErrorKind

The specific kind of error

source_path: Vec<PathSegment>

Path through the source Value where the error occurred

dest_path: Vec<PathSegment>

Path through the target Shape where the error occurred

target_shape: Option<&'static Shape>

The target Shape we were deserializing into (for diagnostics)

source_value: Option<Value>

The source Value we were deserializing from (for diagnostics)

Implementations

impl ValueError

pub fn new(kind: ValueErrorKind) -> Self

Create a new ValueError with empty paths

pub fn with_shape(self, shape: &'static Shape) -> Self

Set the target shape for diagnostics

pub fn with_value(self, value: Value) -> Self

Set the source value for diagnostics

pub fn with_path(self, segment: PathSegment) -> Self

Add a path segment to both paths (prepends since we unwind from error site)

pub fn source_path_string(&self) -> String

Format the source path as a string

pub fn dest_path_string(&self) -> String

Format the dest path as a string

Trait Implementations

impl Debug for ValueError

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

Formats the value using the given formatter.

impl Display for ValueError

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

Formats the value using the given formatter.

impl Error for ValueError

Available on crate feature std only.

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<ReflectError> for ValueError

fn from(err: ReflectError) -> Self

Converts to this type from the input type.
