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)

The input contained a boolean value that was not expected.

§

Unsigned(u64)

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

§

Signed(i64)

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

§

Float(f64)

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

§

Char(char)

The input contained a char that was not expected.

§

Str(&'a str)

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

§

Bytes(&'a [u8])

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

§

Unit

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

§

Option

§

UnitVariant

The input contained a unit variant that was not expected.

§

NewtypeVariant
