Enum InterpError 

pub enum InterpError {
    Problems(Vec<Problem>),
    Cycle(Cycle),
}

Why interpolation failed.

Two shapes because the two failures differ in kind. Everything a document gets wrong is collected and reported together — references are written all over a config, and rediscovering them one run at a time is the experience this avoids. A cycle is the exception: resolution cannot continue past it, so it is an early return and arrives alone.

Variants

Problems(Vec<Problem>)

Cycle(Cycle)

Trait Implementations

impl Debug for InterpError

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

Formats the value using the given formatter.

impl Display for InterpError

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

Formats the value using the given formatter.

impl Error for InterpError

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>)
