Expand description

Unexpected represents an unexpected invocation of any one of the Visitor trait methods.

This is used as an argument to the invalid_type, invalid_value, and invalid_length methods of the Error trait to build error messages.

fn visit_bool<E>(self, v: bool) -> Result<Self::Value, E>
where
    E: de::Error,
{
    Err(de::Error::invalid_type(Unexpected::Bool(v), &self))
}

Variants

Bool(bool)

Tuple Fields

0: bool

The input contained a boolean value that was not expected.

Unsigned(u64)

Tuple Fields

0: u64

The input contained an unsigned integer u8, u16, u32 or u64 that was not expected.

Signed(i64)

Tuple Fields

0: i64

The input contained a signed integer i8, i16, i32 or i64 that was not expected.

Float(f64)

Tuple Fields

0: f64

The input contained a floating point f32 or f64 that was not expected.

Char(char)

Tuple Fields

0: char

The input contained a char that was not expected.

Str(&'a str)

Tuple Fields

0: &'a str

The input contained a &str or String that was not expected.

Bytes(&'a [u8])

Tuple Fields

The input contained a &[u8] or Vec<u8> that was not expected.

Unit

The input contained a unit () that was not expected.

Option

The input contained an Option<T> that was not expected.

NewtypeStruct

The input contained a newtype struct that was not expected.

Seq

The input contained a sequence that was not expected.

Map

The input contained a map that was not expected.

Enum

The input contained an enum that was not expected.

UnitVariant

The input contained a unit variant that was not expected.

NewtypeVariant

The input contained a newtype variant that was not expected.

TupleVariant

The input contained a tuple variant that was not expected.

StructVariant

The input contained a struct variant that was not expected.

Other(&'a str)

Tuple Fields

0: &'a str

A message stating what uncategorized thing the input contained that was not expected.

The message should be a noun or noun phrase, not capitalized and without a period. An example message is “unoriginal superhero”.
