Struct tvix_eval::EvaluationResult

pub struct EvaluationResult {
    pub value: Option<Value>,
    pub errors: Vec<Error>,
    pub warnings: Vec<EvalWarning>,
    pub expr: Option<Expr>,
}

Result of evaluating a piece of Nix code. If evaluation succeeded, a value will be present (and potentially some warnings!). If evaluation failed, errors will be present.

Fields

value: Option<Value>

Nix value that the code evaluated to.

errors: Vec<Error>

Errors that occured during evaluation (if any).

warnings: Vec<EvalWarning>

Warnings that occured during evaluation. Warnings are not critical, but should be addressed either to modernise code or improve performance.

expr: Option<Expr>

AST node that was parsed from the code (on success only).
