Enum FallbackPolicy 

pub enum FallbackPolicy {
    Error,
    FastFallback,
    HeuristicFallback,
}

General fallback behavior for model-backed operations.

Variants

Error

Return a typed error.

FastFallback

Use a fast deterministic fallback.

HeuristicFallback

Use a heuristic fallback.

Trait Implementations

impl Clone for FallbackPolicy

fn clone(&self) -> FallbackPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FallbackPolicy

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

Formats the value using the given formatter.

impl Default for FallbackPolicy

fn default() -> FallbackPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FallbackPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FallbackPolicy

impl PartialEq for FallbackPolicy

fn eq(&self, other: &FallbackPolicy) -> 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.

impl Serialize for FallbackPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
