Enum GeneratorInfo 

pub enum GeneratorInfo {
    Explicit,
    Default,
    Boundary {
        which: BoundaryKind,
    },
    Random {
        seed: Option<u64>,
    },
    Derived {
        expression: String,
    },
}

How a value was produced.

Parallels upstream’s generator metadata. Stored inside Provenance as an option: a value constructed by a caller that doesn’t care about the source leaves it None.

Variants

Explicit

Supplied verbatim by the caller.

Default

Taken from the owning parameter’s default.

Boundary

Picked from the domain’s boundary set.

Fields

which: BoundaryKind

Which boundary was selected.

Random

Drawn pseudo-randomly; seed is recorded when known.

Fields

seed: Option<u64>

RNG seed, if the caller tracked it.

Derived

Computed from a derived parameter’s expression.

Fields

expression: String

Source form of the derivation expression.

Trait Implementations

impl Clone for GeneratorInfo

fn clone(&self) -> GeneratorInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GeneratorInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GeneratorInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GeneratorInfo

fn eq(&self, other: &GeneratorInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GeneratorInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for GeneratorInfo
