Enum RuntimeOptionError 

pub enum RuntimeOptionError {
    OutOfRange {
        field: &'static str,
        value: u64,
        min: u64,
        max: u64,
    },
    TransparentAnchorColor {
        field: &'static str,
        slot: &'static str,
        alpha: u8,
    },
    CapabilityGated {
        field: &'static str,
        detail: GatingDetail,
    },
}

A single, explicit option validation/gating failure.

Variants

OutOfRange

A numeric field is outside its allowed schema range.

Fields

field: &'static str

Canonical field identifier.

value: u64

The offending value.

min: u64

Inclusive minimum.

max: u64

Inclusive maximum.

TransparentAnchorColor

A theme anchor colour (foreground/background) was not fully opaque.

Fields

field: &'static str

Canonical field identifier (theme).

slot: &'static str

The offending palette slot.

alpha: u8

The non-opaque alpha value.

CapabilityGated

The value is schema-valid but unsupported by the active capability profile.

Fields

field: &'static str

Canonical field identifier.

detail: GatingDetail

Specific gating reason.

Implementations

impl RuntimeOptionError

pub const fn field(&self) -> &'static str

The canonical field identifier this error concerns.

pub const fn kind(&self) -> &'static str

A stable machine token for the error kind (used in structured logs).

Trait Implementations

impl Clone for RuntimeOptionError

fn clone(&self) -> RuntimeOptionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeOptionError

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

Formats the value using the given formatter.

impl Display for RuntimeOptionError

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

Formats the value using the given formatter.

impl Eq for RuntimeOptionError

impl Error for RuntimeOptionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RuntimeOptionError

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