Struct ConstError

pub struct ConstError {
    pub signal: u32,
    pub message: String,
}

Structure for holding constant error types.

Fields

signal: u32

Integer tag/signal for the error.

message: String

Error message.

Implementations

impl ConstError

pub fn new(signal: u32, message: impl ToString) -> Self

Define a new error value.

pub fn new_default_signal(message: impl ToString) -> Self

Define a new error value with the default signal.

pub fn as_either(self, ty_ok: impl Into<TypeRowRV>) -> Value

Returns an “either” value with a failure variant.

args: ty_ok: The type of the success variant.

Trait Implementations

impl Clone for ConstError

fn clone(&self) -> ConstError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomConst for ConstError

fn name(&self) -> ValueName

An identifier for the constant.

fn equal_consts(&self, other: &dyn CustomConst) -> bool

Compare two constants for equality, using downcasting and comparing the definitions.

fn get_type(&self) -> Type

Report the type.

fn validate(&self) -> Result<(), CustomCheckFailure>

Check the value.

fn update_extensions( &mut self, _extensions: &WeakExtensionRegistry, ) -> Result<(), ExtensionResolutionError>

Update the extensions associated with the internal values.

impl Debug for ConstError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConstError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<String> for ConstError

fn from(s: String) -> Self

Converts to this type from the input type.

impl FromStr for ConstError

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ConstError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConstError

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

impl Serialize for ConstError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
