Struct EvalContext 

pub struct EvalContext {
    pub expr: Expr,
    pub negate: bool,
}

Convenience wrapper: evaluate expr against a raw VCF line and return per-sample booleans. Equivalent to eval_expr but returns EvalError wrapped in a Box<dyn Error>.

Fields

expr: Expr

negate: bool

Implementations

impl EvalContext

pub fn new(expr: Expr, negate: bool) -> Self

negate = true for -e (exclude) mode: a sample PASSES if the expr is FALSE.

pub fn eval_line( &self, line: &str, n_samples: usize, ) -> Result<SampleResult, EvalError>

Evaluate against one VCF data line; returns per-sample boolean (true → rewrite).
