Error from network IO or invalid operation.

Variants

InvalidDateTime

Invalid time was used to build Date or DateTime.

IO(Error)

Network error.

InvalidCast

Tried to cast to wrong type.

Fields

from: &'static str

to: &'static str

InvalidCastList(&'static str)

Tried to cast a list to wrong type.

IndexOutOfBounds

Tried to access an index which is out of range.

Fields

length: usize

index: usize

InvalidOperation

Invalid operation to a wrong type.

Fields

operator: &'static str

operand_type: &'static str

expected: Option<&'static str>

LengthMismatch

Length of dictionary key and value do not match.

Fields

key_length: usize

value_length: usize

NoSuchColumn(String)

Tried to get non-existing column.

InsertWrongElement

Tried to insert or push wrong element.

Fields

is_insert: bool

destination: &'static str

expected: &'static str

PopFromEmptyList

Tried to pop from empty list.

Object(K)

Tried to convert but coluld not.

Implementations

impl Error

pub fn into_inner(self) -> Option<K>

Comsume error and retrieve original object returned from some operation. None is returned if the error does not contain K object.

use kdbplus::ipc::*;

let int = K::new_int(777);
match int.flip(){
  Ok(_) => eprintln!("miracle!!"),
  Err(original_) => {
    let original = original_.into_inner().unwrap();
    assert_eq!(original.get_int().unwrap(), 777);
  }
}

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 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<Error> for Error

fn from(error: IOError) -> 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.
