Enum ndata::data::Data

pub enum Data {
    DObject(usize),
    DArray(usize),
    DBytes(usize),
    DString(String),
    DBoolean(bool),
    DFloat(f64),
    DInt(i64),
    DNull,
}

Represents an NData value

DObject, DArray, and DBytes are considered instances and the clone() function will return a reference to the same instance.

Variants

DObject(usize)

Represents an existing instance of ndata::dataobject::DataObject, where data_ref is the value of the DataObject’s data_ref field.

let d = Data::DObject(data_ref);

DArray(usize)

Represents an existing instance of ndata::dataobject::DataArray, where data_ref is the value of the DataArray’s data_ref field.

let d = Data::DArray(data_ref);

DBytes(usize)

Represents an existing instance of ndata::dataobject::DataBytes, where data_ref is the value of the DataBytes’s data_ref field.

let d = Data::DBytes(data_ref);

DString(String)

Contains a String value

let d = Data::DString("hello world".to_owned());

DBoolean(bool)

Contains a bool value

let d = Data::DBoolean(true);

DFloat(f64)

Contains an f64 value

let d = Data::DFloat(99.99);

DInt(i64)

Contains an i64 value

let d = Data::DInt(99);

DNull

Contains no value

let d = Data::DNull;

Implementations

impl Data

pub fn is_number(&self) -> bool

Returns true if the value is of type DInt or DFloat.

pub fn is_int(&self) -> bool

Returns true if the value is of type DInt.

pub fn is_float(&self) -> bool

Returns true if the value is of type DFloat.

pub fn is_string(&self) -> bool

Returns true if the value is of type DString.

pub fn is_boolean(&self) -> bool

Returns true if the value is of type DBoolean.

pub fn is_object(&self) -> bool

Returns true if the value is of type DObject.

pub fn is_array(&self) -> bool

Returns true if the value is of type DArray.

pub fn is_bytes(&self) -> bool

Returns true if the value is of type DBytes.

pub fn is_null(self) -> bool

Returns true if the value is of type DNull.

pub fn int(&self) -> i64

Returns the underlying i64 value, or panics if not DInt.

pub fn float(&self) -> f64

Returns the underlying f64 value, or panics if not DFloat.

pub fn boolean(&self) -> bool

Returns the underlying bool value, or panics if not DBoolean.

pub fn string(&self) -> String

Returns the underlying String value, or panics if not DString.

pub fn object(&self) -> DataObject

Returns a new DataObject representing the underlying object instance, or panics if not DObject.

pub fn array(&self) -> DataArray

Returns a new DataArray representing the underlying array instance, or panics if not DArray.

pub fn bytes(&self) -> DataBytes

Returns a new DataBytes representing the underlying byte buffer instance, or panics if not DBytes.

pub fn as_string(a: Data) -> String

Returns a String representation of the underlying value.

pub fn equals(a: Data, b: Data) -> bool

Trait Implementations

impl Clone for Data

fn clone(&self) -> Self

Returns a copy of the value.

Since DObject, DArray, and DBytes are references to instances, the resulting Data will point to the same instance as the original.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.

impl Default for Data

The default for ndata.Data is DNull.

fn default() -> Data

Returns the “default value” for a type.
