Enum ParseError

pub enum ParseError<T> {
    BadFd(SourcePos, SourcePos),
    BadIdent(String, SourcePos),
    BadSubst(Token, SourcePos),
    Unmatched(Token, SourcePos),
    IncompleteCmd(&'static str, SourcePos, &'static str, SourcePos),
    Unexpected(Token, SourcePos),
    UnexpectedEOF,
    Custom(T),
}

The error type which is returned from parsing shell commands.

Variants

BadFd(SourcePos, SourcePos)

Encountered a word that could not be interpreted as a valid file descriptor. Stores the start and end position of the invalid word.

BadIdent(String, SourcePos)

Encountered a Token::Literal where expecting a Token::Name.

BadSubst(Token, SourcePos)

Encountered a bad token inside of ${...}.

Unmatched(Token, SourcePos)

Encountered EOF while looking for a match for the specified token. Stores position of opening token.

IncompleteCmd(&'static str, SourcePos, &'static str, SourcePos)

Did not find a reserved keyword within a command. The first String is the command being parsed, followed by the position of where it starts. Next is the missing keyword followed by the position of where the parse expected to have encountered it.

Unexpected(Token, SourcePos)

Encountered a token not appropriate for the current context.

UnexpectedEOF

Encountered the end of input while expecting additional tokens.

Custom(T)

A custom error returned by the AST builder.

Trait Implementations

impl<T: Clone> Clone for ParseError<T>

fn clone(&self) -> ParseError<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ParseError<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for ParseError<T>

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

Formats the value using the given formatter.

impl<T: Error> Error for ParseError<T>

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

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

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<T> From<T> for ParseError<T>

fn from(err: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for ParseError<T>

fn eq(&self, other: &ParseError<T>) -> 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.
