Enum filecheck::Error

pub enum Error {
    Syntax(String),
    UndefVariable(String),
    Backref(String),
    DuplicateDef(String),
    Regex(Error),
}

A filecheck error.

Variants

Syntax(String)

A syntax error in a check line.

UndefVariable(String)

A check refers to an undefined variable.

The pattern contains $foo where the foo variable has not yet been defined. Use $$ to match a literal dollar sign.

Backref(String)

A pattern contains a back-reference to a variable that was defined in the same pattern.

For example, check: Hello $(world=.*) $world. Backreferences are not supported. Often the desired effect can be achieved with the sameln check:

check: Hello $(world=[^ ]*)
sameln: $world

DuplicateDef(String)

A pattern contains multiple definitions of the same variable.

Regex(Error)

An error in a regular expression.

Use cause() to get the underlying Regex library error.

Trait Implementations

impl Fail for Error

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for Error

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

Formats the value using the given formatter.

impl Debug for Error

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl From<Error> for Error

fn from(e: Error) -> Error

Performs the conversion.
