Enum NestingError 

pub enum NestingError {
    ZeroDepthLimit,
    ZeroOutputLimit,
    DepthExceeded {
        depth: usize,
        max_depth: usize,
    },
    OutputExceeded {
        max_output: usize,
    },
}

Failure while expanding a finite nested serial pattern.

Variants

ZeroDepthLimit

The requested limit admitted no nesting depth.

ZeroOutputLimit

The requested limit admitted no output.

DepthExceeded

Expansion encountered a deeper group than permitted.

Fields

depth: usize

Observed depth at the failing group.

max_depth: usize

Maximum permitted depth.

OutputExceeded

Expansion would emit more terminal values than permitted.

Fields

max_output: usize

Maximum permitted output cardinality.

Trait Implementations

impl Clone for NestingError

fn clone(&self) -> NestingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NestingError

impl Debug for NestingError

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

Formats the value using the given formatter.

impl Display for NestingError

impl Eq for NestingError

impl Error for NestingError

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 NestingError

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

Equality operator ==.

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

Inequality operator !=.
