Struct Discriminant

pub struct Discriminant {
    pub expr: String,
    pub value: String,
}

The value that distinguishes a variant in an Enum from other variants.

Fields

expr: String

The expression that produced the discriminant.

Unlike value, this preserves the original formatting (eg suffixes, hexadecimal, and underscores), making it unsuitable to be machine interpreted.

In some cases, when the value is too complex, this may be "{ _ }". When this occurs is unstable, and may change without notice.

value: String

The numerical value of the discriminant. Stored as a string due to JSON’s poor support for large integers, and the fact that it would need to store from i128::MIN to u128::MAX.

Trait Implementations

impl Clone for Discriminant

fn clone(&self) -> Discriminant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Discriminant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Discriminant

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Discriminant

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Discriminant

fn eq(&self, other: &Discriminant) -> 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 Discriminant

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 Discriminant

impl StructuralPartialEq for Discriminant

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
