Enum HooksError 

pub enum HooksError {
    CannotAddEntryByIndex(usize),
    KeyNotFound(MapKeySelector),
    FieldNotFound(Cow<'static, str>),
    ValueNotSerializable(String),
    IndexNotFound(usize),
    CannotFlattenUnsupportedDataType(&'static str),
}

Kinds of recoverable errors.

See Hooks::on_scope_error for more info on handling recoverable errors.

Variants

CannotAddEntryByIndex(usize)

Cannot add a map entry by specifying an index, please specify key value.

This error occurs when trying to add a map entry, but specifying an index instead of an actual key in the map key selector.

KeyNotFound(MapKeySelector)

This key is not found in the map.

FieldNotFound(Cow<'static, str>)

This field is not found in the struct.

ValueNotSerializable(String)

This value is not serializable.

This error occurs when trying to replace a value using compound scope methods (e.g. on a struct or map scope), and passing in a Value that is non-primitive. Non-primitive values, like structs, maps, tuples, are represented by their metadata, which is obviously not sufficient to serialize them.

IndexNotFound(usize)

This index was not found in the sequence.

CannotFlattenUnsupportedDataType(&'static str)

Flattening was attempted on a struct field that does not contain a struct or a map.

Trait Implementations

impl Debug for HooksError

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

Formats the value using the given formatter.

impl Display for HooksError

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

Formats the value using the given formatter.

impl Error for HooksError

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 PartialEq for HooksError

fn eq(&self, other: &HooksError) -> 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.
