Enum ResolveError 

pub enum ResolveError {
    Unknown {
        input: String,
        suggestions: Vec<String>,
    },
    Ambiguous {
        input: String,
        candidates: Vec<String>,
    },
}

Errors produced by Resolver::resolve.

Variants

Unknown

The input did not match any registered command. suggestions contains up to three canonically close alternatives determined by edit distance.

Fields

input: String

The original (untrimmed) input string.

suggestions: Vec<String>

Up to three canonical names that are close to input. May be empty.

Ambiguous

The input matched more than one command as a prefix, making it ambiguous. The candidates field lists the canonical names of the matching commands.

Fields

input: String

The original (untrimmed) input string.

candidates: Vec<String>

Canonical names of all commands that matched the prefix.

Trait Implementations

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Error for ResolveError

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 From<ResolveError> for ParseError

fn from(source: ResolveError) -> Self

Converts to this type from the input type.

impl PartialEq for ResolveError

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