Enum PatternError 

pub enum PatternError {
    Empty,
    MissingName,
    UnbalancedParens(String),
    IllegalChar(String),
}

Errors from parsing a raw string with ToolPattern::parse.

Variants

Empty

Input was empty or all whitespace.

MissingName

The tool name part was empty (e.g. (args) with nothing before).

UnbalancedParens(String)

Parentheses were unbalanced or appeared out of order.

IllegalChar(String)

Contained a character that the CLI disallows in pattern values (comma splits the argv, control chars can break the shell).

Trait Implementations

impl Debug for PatternError

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

Formats the value using the given formatter.

impl Display for PatternError

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

Formats the value using the given formatter.

impl Error for PatternError

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 PatternError

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