Enum ResolveError 

#[non_exhaustive]
pub enum ResolveError {
    BudgetExceeded {
        limit: Limit,
    },
    DuplicateUnit {
        unit: UnitId,
    },
}

Why a resolution run stopped without a result.

Name errors in the program are not ResolveErrors: they are Diagnostics in a successful result. A run fails only when the input is unusable as a whole or exceeds a Budget.

Examples

use hir_lang::UnitId;
use resolve_lang::ResolveError;

let e = ResolveError::DuplicateUnit { unit: UnitId::new(3) };
assert_eq!(e.to_string(), "two units of the program have the id 3");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BudgetExceeded

The program reached a budget limit. Raise the limit with Budget if the input is trusted, or reject the input.

Fields

limit: Limit

The limit reached.

DuplicateUnit

Two units share a UnitId; DefIds could not tell them apart. Give every unit of a program a distinct id.

Fields

unit: UnitId

The shared id.

impl Eq for ResolveError

impl Error for ResolveError

fn source(&self) -> Option<&(dyn Error + 'static)>
