Enum AssertionPredicate 

pub enum AssertionPredicate {
    Eq(String),
    NotNull,
    IsNull,
    Gte(f64),
    Lte(f64),
    Contains(String),
    MalformedBound {
        key: String,
        raw: String,
    },
    MinRows(u64),
}

Predicate for field assertion checks.

Variants

Eq(String)

Field must equal this value (string comparison).

NotNull

Field must not be null/absent.

IsNull

Field must be null/absent.

Gte(f64)

Numeric: field >= threshold.

Lte(f64)

Numeric: field <= threshold.

Contains(String)

String: field contains substring.

MalformedBound

A numeric bound (gte: / lte:) whose value is not a number.

Carried rather than dropped, and ALWAYS fails: the previous as_f64().unwrap_or(0.0) silently turned lte: "5" — or any unresolved placeholder — into <= 0, which then failed against perfectly good data with a message quoting a threshold the author never wrote. A bound nobody can evaluate must say so, not pick zero.

Fields

key: String

raw: String

MinRows(u64)

Body-level: result must contain at least N rows (element_count() >= N). Use to make a SELECT failsafe — empty result sets surface as a hard error instead of silently passing per-row assertions vacuously. Field name is ignored for this predicate.

Trait Implementations
