Implementations

impl BarcodeScannerError

pub fn new(code: impl Into<String>, message: impl Into<String>) -> Self

Creates a portable barcode scanner error payload.

code should be a stable, machine-readable reason such as unsupported, permission_denied, or timeout. message should be a concise human-readable explanation suitable for logs or developer-facing diagnostics.

pub fn unsupported(operation: impl Into<String>) -> Self

Creates the standard unsupported-operation error for this capability.

operation should name the attempted barcode scanner operation. Use this from hosts that implement the capability contract but cannot provide this operation on the current platform or hardware.

Trait Implementations

impl Clone for BarcodeScannerError

fn clone(&self) -> BarcodeScannerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BarcodeScannerError

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

Formats the value using the given formatter.

impl Default for BarcodeScannerError

fn default() -> BarcodeScannerError

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BarcodeScannerError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BarcodeScannerError

fn eq(&self, other: &BarcodeScannerError) -> 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 BarcodeScannerError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
