Enum Error

pub enum Error {
    StackUnderflow,
    TypeMismatch,
    UnrecognizedFormatOption(char),
    InvalidVariableName(char),
    InvalidParameterIndex(char),
    MalformedCharacterConstant,
    IntegerConstantOverflow,
    MalformedIntegerConstant,

}

An error from interpreting a parameterized string.

Variants

StackUnderflow

Data was requested from the stack, but the stack didn’t have enough elements.

TypeMismatch

The type of the element(s) on top of the stack did not match the type that the operator wanted.

UnrecognizedFormatOption(char)

An unrecognized format option was used.

InvalidVariableName(char)

An invalid variable name was used.

InvalidParameterIndex(char)

An invalid parameter index was used.

MalformedCharacterConstant

A malformed character constant was used.

IntegerConstantOverflow

An integer constant was too large (overflowed an i32)

MalformedIntegerConstant

A malformed integer constant was used.

FormatWidthOverflow

A format width constant was too large (overflowed a usize)

FormatPrecisionOverflow

A format precision constant was too large (overflowed a usize)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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)>

Returns the lower-level source of this error, if any.

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<Error> for Error

fn from(val: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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 Eq for Error

impl StructuralPartialEq for Error
