Enum SchemaMaxSerializedSizeError

pub enum SchemaMaxSerializedSizeError {
    Overflow,
    Recursive,
    MissingDefinition(Declaration),
}

Possible error when calculating theoretical maximum size of encoded type T.

Variants

Overflow

The theoretical maximum size of the encoded value overflows usize.

This may happen for nested dynamically-sized types such as Vec<Vec<u8>> whose maximum size is 4 + u32::MAX * (4 + u32::MAX).

Recursive

The type is recursive and thus theoretical maximum size is infinite.

Simple type in which this triggers is struct Rec(Option<Box<Rec>>).

MissingDefinition(Declaration)

Some of the declared types were lacking definition making it impossible to calculate the size.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

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.
