Struct WriteOutcome 

pub struct WriteOutcome {
    pub success: bool,
    pub error_message: Option<String>,
}

The result of one crate::Driver::write call that reached the driver.

Kept distinct from a crate::DriverError: a driver (or the DCS/PLC behind it) rejecting a write — the tag is read-only, the value is out of range, permissions — is a normal, expected outcome of the call succeeding at the transport level, not a connection/operation failure. This shape mirrors bhtune_db::models::TuneWriteRow’s own success/error_message columns exactly, so a caller recording a write-back audit row can copy this outcome straight into that table with no translation.

Fields

success: bool

error_message: Option<String>

Implementations

impl WriteOutcome

pub fn success() -> WriteOutcome

A write the driver accepted outright.

pub fn failure(error_message: impl Into<String>) -> WriteOutcome

A write the driver rejected, with its own explanation of why.

Trait Implementations

impl Clone for WriteOutcome

fn clone(&self) -> WriteOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteOutcome

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

Formats the value using the given formatter.

impl PartialEq for WriteOutcome

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