Struct WriteOptions 

pub struct WriteOptions {
    pub fsync: bool,
}

Options controlling how a write touches the filesystem.

Default values match the previous (pre-Phase-A) std::fs::write behaviour: atomic at the rename, but not durable against power loss. Set fsync: true to force the data to stable storage before the write returns.

Designed to be Copy + Default + serde::* so it can be piped through the mutation builders, configured from env vars or config files, or surfaced over a Tauri command.

Fields

fsync: bool

fsync the temp file’s data, then fsync the parent directory’s metadata, before considering the write complete. Adds one or two disk-flush IOs per write — typically 1–10ms on consumer SSDs and 10–50ms on spinning disks. Required for durable mutations (e.g. a long-lived Tauri app) that need to survive sudden power loss with the change preserved.

Implementations

impl WriteOptions

pub fn durable() -> Self

Convenience: opts with fsync set to true.

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() -> WriteOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WriteOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for WriteOptions

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
