Struct CacheTtl 

pub struct CacheTtl(/* private fields */);

A nonnegative final cache TTL that retains its exact JSON-integer spelling.

Implementations

impl CacheTtl

pub fn milliseconds(value: u64) -> Self

Creates a nonnegative TTL in milliseconds.

pub fn as_str(&self) -> &str

Returns the exact nonnegative JSON-integer wire spelling.

pub fn try_as_millis(&self) -> Result<u64, CacheTtlConversionError>

Converts this wire value into the bounded local millisecond domain.

This is intentionally checked: the final schema has no maximum, while local duration APIs accept at most u64 milliseconds.
