Enum BinaryCachePolicyKind 

pub enum BinaryCachePolicyKind {
    KeepCompatible,
    DiscardOnUpgrade,
    NeverDiscard,
}

Built-in binary cache policy variants, selectable via config.

Config examples

{ "binary_cache_policy": "keep_compatible" }
{ "binary_cache_policy": "discard_on_upgrade" }
{ "binary_cache_policy": "never_discard" }

Variants

KeepCompatible

Keep the cache as long as the current binary satisfies min_binary_version. Recommended for most apps — opt in via "binary_cache_policy": "keep_compatible".

DiscardOnUpgrade

Discard when current_binary > min_binary_version. This is the default, preserving pre-0.0.2 semantics.

Note: this detects “binary newer than min”, not actual binary changes (e.g., rebuild at same version, downgrade). True change detection would require persisting the previous binary version (deferred).

NeverDiscard

Never discard based on binary version. Only the safety check (binary < min) still applies.

Trait Implementations

impl BinaryCachePolicy for BinaryCachePolicyKind

fn should_discard( &self, current_binary: &Version, cached_meta: &HotswapMeta, _previous_binary: Option<&Version>, ) -> bool

Return true to discard the cached bundle and fall back to embedded assets.

impl Clone for BinaryCachePolicyKind

fn clone(&self) -> BinaryCachePolicyKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BinaryCachePolicyKind

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

Formats the value using the given formatter.

impl Default for BinaryCachePolicyKind

fn default() -> BinaryCachePolicyKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BinaryCachePolicyKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BinaryCachePolicyKind

fn eq(&self, other: &BinaryCachePolicyKind) -> 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 BinaryCachePolicyKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
