Enum Value 

#[non_exhaustive]
pub enum Value {
    Null,
    Bool(bool),
    Int16(i16),
    Int32(i32),
    Int64(i64),
    Float32(f32),
    Float64(f64),
    String(String),
    Binary(Vec<u8>),
    DateTime(f64),
    Guid([u8; 16]),
    Xml(String),
}

One attribute value. Marked #[non_exhaustive] because future versions may add variants (e.g. Date / Time / DateTimeOffset once we move off the f64-days representation, or Json / Decimal for richer schemas) without that counting as a SemVer-breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Null

Bool(bool)

Int16(i16)

Int32(i32)

Int64(i64)

Float32(f32)

Float64(f64)

String(String)

Binary(Vec<u8>)

DateTime(f64)

Days since 1899-12-30 00:00:00 (Esri convention). See module docs.

Guid([u8; 16])

16-byte UUID, raw bytes (no string formatting).

Xml(String)

XML payload, stored verbatim.

Implementations

impl Value

pub fn ty(&self) -> Option<ValueType>

Returns None for Value::Null, otherwise the type of the variant.

pub fn is_null(&self) -> bool

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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.
