Enum 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 Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
