Enum ParseWarning 

pub enum ParseWarning {
    Unknown(String),
    InvalidAssignment(&'static ExperimentalOption, String),
    InvalidAssignmentAll(String),
    DeprecatedDefault(&'static ExperimentalOption),
    DeprecatedDiscard(&'static ExperimentalOption),
}

Warnings that can happen while parsing experimental options.

Variants

Unknown(String)

The given identifier doesn’t match any known experimental option.

InvalidAssignment(&'static ExperimentalOption, String)

The assignment wasn’t valid. Only true or false is accepted.

InvalidAssignmentAll(String)

The assignment for “all” wasn’t valid. Only true or false is accepted.

DeprecatedDefault(&'static ExperimentalOption)

This experimental option is deprecated as this is now the default behavior.

DeprecatedDiscard(&'static ExperimentalOption)

This experimental option is deprecated and will be removed in the future.

Implementations

impl ParseWarning

pub fn code(&self) -> &'static str

A code to represent the variant.

This may be used with crates like miette to provide error codes.

pub fn help(&self) -> Option<String>

Provide some help depending on the variant.

This may be used with crates like miette to provide a help message.

Trait Implementations

impl Clone for ParseWarning

fn clone(&self) -> ParseWarning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseWarning

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

Formats the value using the given formatter.

impl Display for ParseWarning

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

Formats the value using the given formatter.

impl Error for ParseWarning

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 ParseWarning

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