Struct CacheKey 

pub struct CacheKey {
    pub schema_version: u32,
    pub platform: String,
    pub ir_hash: ContentHash,
}

Cache key: (schema_version, backend_platform, ir_content_hash).

Three-part: the schema version guards against trait evolution, the platform name guards against backend-specific output, the IR hash identifies the input.

Fields

schema_version: u32

platform: String

ir_hash: ContentHash

Implementations

impl CacheKey

pub fn for_resource<B: Backend>(backend: &B, input: &ResourceInput<'_>) -> Self

Construct a key for the current schema and a (backend, resource).

Uses the source resource’s content_hash and the backend’s platform() as the two variable parts.
