Enum CacheTier 

pub enum CacheTier {
    Immutable,
    SemiStable,
    Volatile,
    NeverCache,
}

Classification of an RPC method’s caching behavior.

Variants

Immutable

Results that never change (e.g., finalized block data, confirmed tx receipts). Very long TTL (1 hour).

SemiStable

Results that change infrequently (e.g., eth_chainId, eth_getCode). Medium TTL (5 minutes).

Volatile

Results that change frequently (e.g., eth_blockNumber, eth_gasPrice). Short TTL (2 seconds).

NeverCache

Write methods and subscription calls. Never cached.

Implementations

impl CacheTier

pub fn default_ttl(&self) -> Option<Duration>

Return the default TTL associated with this tier.

Trait Implementations

impl Clone for CacheTier

fn clone(&self) -> CacheTier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheTier

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

Formats the value using the given formatter.

impl PartialEq for CacheTier

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