Enum CacheWriteTier 

pub enum CacheWriteTier {
    FiveMin,
    OneHour,
}

Which cache-write TTL tier a prompt-cache write was billed at.

Anthropic bills cache writes at a per-TTL premium over the base input rate: the default 5-minute ephemeral tier is ~1.25× base input, and the opt-in 1-hour tier (cache_control: {"type": "ephemeral", "ttl": "1h"}) is ~2× (platform.claude.com/docs/en/build-with-claude/prompt-caching § Economics). ModelPricing::cache_write_per_million is the 5-minute rate; ModelPricing::cache_write_rate_per_million resolves either tier.

Variants

FiveMin

The default ephemeral TTL — cache_control with no ttl field. ~1.25×.

OneHour

The opt-in 1-hour TTL — cache_control with "ttl": "1h". ~2×.

Trait Implementations

impl Clone for CacheWriteTier

fn clone(&self) -> CacheWriteTier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CacheWriteTier

impl Debug for CacheWriteTier

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

Formats the value using the given formatter.

impl Default for CacheWriteTier

fn default() -> CacheWriteTier

Returns the “default value” for a type.

impl Eq for CacheWriteTier

impl PartialEq for CacheWriteTier

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