Struct OptionConflict 

pub struct OptionConflict {
    pub name: String,
    pub existing: Box<OptionDef>,
    pub attempted: Box<OptionDef>,
}

Raised when an option name is attached with a definition that disagrees with the one already recorded for that name. Surfacing this at attach time is the runtime-verifiable guarantee that every uniquely-named option parses one way.

Fields

name: String

existing: Box<OptionDef>

attempted: Box<OptionDef>

Trait Implementations

impl Clone for OptionConflict

fn clone(&self) -> OptionConflict

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionConflict

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

Formats the value using the given formatter.

impl Display for OptionConflict

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

Formats the value using the given formatter.

impl Eq for OptionConflict

impl Error for OptionConflict

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 OptionConflict

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