Enum Error

#[non_exhaustive]
pub enum Error {
    Io(Error),
    Utf8(Utf8Error),
    FromBytesWithNul(FromBytesWithNulError),
    Boxed(Box<dyn Error>),
    Throw(ThrowObject),
    ClassNotFound(ClassNotFoundError),
    ArgumentCount(ArgumentCountError),
    InitializeObject(InitializeObjectError),
    ExpectType(ExpectTypeError),
    NotImplementThrowable(NotImplementThrowableError),
}

Crate level Error, which also can become an exception in php.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

The error type for I/O operations.

Utf8(Utf8Error)

Errors which can occur when attempting to interpret a sequence of u8 as a string.

FromBytesWithNul(FromBytesWithNulError)

An error indicating that a nul byte was not in the expected position.

Boxed(Box<dyn Error>)

Owned boxed dynamic error.

Throw(ThrowObject)

Owned exception object.

ClassNotFound(ClassNotFoundError)

Class not found, get the class by name failed, etc.

ArgumentCount(ArgumentCountError)

Throw when actual arguments count is not greater than expect in calling functions.

InitializeObject(InitializeObjectError)

Failed to initialize object.

ExpectType(ExpectTypeError)

Expect type is not the actual type.

NotImplementThrowable(NotImplementThrowableError)

Failed when the object isn’t implement PHP Throwable.

Implementations

impl Error

pub fn boxed(e: impl Into<Box<dyn Error>> + 'static) -> Self

Wrap the dynamic error into Boxed.

pub fn throw(t: impl Throwable) -> Self

Transfer Throwable item to exception object internally, and wrap it into Throw.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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
