Enum serde_postgres::DeError

pub enum DeError {
    Message(String),
    UnknownField,
    InvalidType(String),
    UnsupportedType,
}

This type represents all possible error that can occur when deserializing postgres rows.

Variants

Message(String)

A custom defined error occurred. Typically coming from serde.

UnknownField

Row contained a field unknown to the data structure.

InvalidType(String)

Row's column type was different from the Rust data structure.

UnsupportedType

Rust data structure contained a type unsupported by serde_postgres.

Trait Implementations

impl Clone for DeError

fn clone(&self) -> DeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeError

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

Formats the value using the given formatter.

impl Display for DeError

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

Formats the value using the given formatter.

impl Error for DeError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Error for DeError

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl PartialEq<DeError> for DeError

fn eq(&self, other: &DeError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DeError) -> bool

This method tests for !=.
