Why a payload body is not a value of its type. The value is dropped and its handler does not run.

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.

UnexpectedEnd

The body ends inside a value.

VarIntTooLong

A VarInt of more than 5 bytes, or a VarLong of more than 10.

NegativeLength

A length or count below zero.

Fields

length: i32

The length as read.

LengthOverLimit

A length or count past its bound.

Fields

length: u32

The length as read.

limit: u32

The most the codec accepts there.

Utf8

A string that is not UTF-8.

TooDeep

Values nested deeper than PAYLOAD_MAX_DEPTH.

InvalidDiscriminant

A boolean, option or enum tag its type does not have.

Fields

value: i32

The tag as read.

NonFinite

A number that must be finite is NaN or infinite.

BudgetExhausted

The value would allocate past the reader’s budget.

Trailing

Bytes left over after the value.

Fields

bytes: u64

How many bytes follow the value.

InvalidValue

A value its own codec refuses (a number outside its domain, an unknown id).
