Struct SchemaCacheBuilder 

pub struct SchemaCacheBuilder { /* private fields */ }

Builder for constructing a SchemaCache with sensible defaults.

Defaults:

• cache_dir: ensure_cache_dir()
• force_fetch: false
• ttl: DEFAULT_SCHEMA_CACHE_TTL (12 hours)

Examples

let cache = SchemaCache::builder().build();
let cache = SchemaCache::builder().force_fetch(true).ttl(Duration::from_secs(3600)).build();

Implementations

impl SchemaCacheBuilder

pub fn cache_dir(self, dir: PathBuf) -> Self

Override the default cache directory.

pub fn force_fetch(self, force: bool) -> Self

When true, bypass cache reads and always fetch from the network. Fetched schemas are still written to the cache.

pub fn ttl(self, ttl: Duration) -> Self

Override the default TTL for cached schemas.

pub fn cache_dir_or_default(&self) -> PathBuf

Returns the cache directory that will be used, or ensure_cache_dir() if none was explicitly set.

Useful when callers need the resolved path before calling build.

pub fn build(self) -> SchemaCache

Build the SchemaCache.
