Struct WriteOptions 

pub struct WriteOptions {
    pub cache_mode: Option<CacheMode>,
    pub ttl: u64,
    pub update_ttl: bool,
}

Options for write operations.

Specifies optional parameters that control write behavior, including caching and time-to-live (TTL) expiration.

Fields

cache_mode: Option<CacheMode>

Cache mode for the write operation.

ttl: u64

Time-to-live in hours (0 = no expiration).

update_ttl: bool

Whether to update TTL on existing records.

Implementations

impl WriteOptions

pub fn new() -> Self

Creates a new WriteOptions with default settings.

pub fn with_cache_mode(self, cache_mode: CacheMode) -> Self

Sets the cache mode.

pub fn with_ttl(self, ttl_hours: u64) -> Self

Sets the time-to-live in hours.

pub fn with_update_ttl(self, update_ttl: bool) -> Self

Sets whether to update TTL on existing records.

pub fn evict_after_write() -> Self

Creates WriteOptions with evict-after-write cache mode.

pub fn with_expiration(ttl_hours: u64) -> Self

Creates WriteOptions with a TTL.

pub fn expiration_time_ms(&self, current_time_ms: u64) -> u64

Returns the expiration time in milliseconds from now, or 0 if no TTL.

pub fn has_ttl(&self) -> bool

Returns whether a TTL is configured.

pub fn get_expiration_time(&self) -> u32

Returns the packed expiration_time (hours since epoch) for use in BinEntry.

Returns 0 if no TTL is set. Uses noxu_util::ttl_hours_to_expiration to compute the expiration time relative to now.

Trait Implementations

impl Clone for WriteOptions

fn clone(&self) -> WriteOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteOptions

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

Formats the value using the given formatter.

impl Default for WriteOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for WriteOptions

impl PartialEq for WriteOptions

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