Enum IrError 

pub enum IrError {
    InvalidRepeatBounds {
        min: usize,
        max: usize,
    },
    DuplicateCapture(CaptureId),
    MissingAssertion(AssertionId),
    AssertionCycle(Vec<AssertionId>),
    UnsupportedExtension(String),
}

A construction failure for pattern IR.

Variants

InvalidRepeatBounds

A repeat’s minimum exceeds its maximum.

Fields

min: usize

Requested minimum.

max: usize

Requested finite maximum.

DuplicateCapture(CaptureId)

A capture identifier occurs more than once.

MissingAssertion(AssertionId)

An assertion refers to a definition that was not supplied.

AssertionCycle(Vec<AssertionId>)

Assertion references form a cycle.

UnsupportedExtension(String)

An extension is unavailable on the selected target engine.

Trait Implementations

impl Clone for IrError

fn clone(&self) -> IrError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IrError

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

Formats the value using the given formatter.

impl Display for IrError

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

Formats the value using the given formatter.

impl Eq for IrError

impl Error for IrError

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 IrError

fn eq(&self, other: &IrError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
