Struct EvalError 

pub struct EvalError {
    pub msg: String,
    pub info: Option<Box<Diagnostic>>,
}

An evaluation error. info carries the structured diagnostic when the failure site had one at hand (a deferred-parse error’s full Diagnostic, or a place reference’s span); bindings surface it without re-deriving positions from the message.

Fields

msg: String

info: Option<Box<Diagnostic>>

Trait Implementations

impl Clone for EvalError

fn clone(&self) -> EvalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl PartialEq for EvalError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
