ValidationResult

Enum ValidationResult 

Source
pub enum ValidationResult {
    Passed,
    Failed {
        message: String,
        violations: Vec<String>,
    },
    Warning {
        message: String,
        underlying: Box<Self>,
    },
}
Expand description

The outcome of validating a value against a parameter or constraint.

See SRD-0004 §ValidationResult. The Warning variant is flattened by construction (never Warning { underlying: Warning { .. } }); callers should use Self::warn rather than constructing the variant directly.

Variants§

§

Passed

The value passed all checks.

§

Failed

The value failed at least one check.

Fields

§message: String

High-level summary of the failure.

§violations: Vec<String>

Per-check violation messages (in encounter order).

§

Warning

The value is acceptable but worth flagging. Exactly one level of warning may wrap an inner result.

Fields

§message: String

High-level summary of the warning.

§underlying: Box<Self>

The wrapped result (never itself a Warning).

Implementations§

Source§

impl ValidationResult

Source

pub const fn passed() -> Self

Construct a passing result. Provided for symmetry with the other constructors.

Source

pub fn failed(message: impl Into<String>, violations: Vec<String>) -> Self

Construct a failing result.

Source

pub fn warn(message: impl Into<String>, inner: Self) -> Self

Wrap an inner result with a warning. Flattens nested warnings.

If inner is itself a Warning, its own inner result is lifted so the returned value has exactly one warning layer. Messages from discarded inner warnings are lost; use the outer message to carry anything the caller needs to preserve.

Source

pub fn is_passed(&self) -> bool

true when the effective outcome is a pass (either Passed or a warning whose underlying result is Passed).

Source

pub fn is_failed(&self) -> bool

true when the effective outcome is a failure.

Source

pub fn violations(&self) -> &[String]

Borrow the violation list, if any. Descends one level of warning.

Source

pub fn message(&self) -> Option<&str>

Borrow the top-level summary message, if any.
