Struct flowcore::model::datatype::DataType

pub struct DataType { /* private fields */ }

DataType is just a String defining what data type is being used

Implementations

impl DataType

pub fn valid(&self) -> Result<()>

Determine if a datatype specified in a flow is a valid datatype or not

pub fn is_array(&self) -> bool

Return if this datatype is an array or not

pub fn is_generic(&self) -> bool

Return true if this datatype is generic (not specified at compile time and can contain any other datatype) or not

pub fn array_type(&self) -> Option<DataType>

If an Array –> Return Option of the DataType the array holds If Generic –> Return Generic If not an Array –> Return None

pub fn value_type(value: &Value) -> DataType

Return the DataType for a Json Value, including nested values in arrays or maps

pub fn type_array_order(&self) -> i32

Determine how deeply nested in arrays this DataType is. If not an array, returns 0

This is used at compile time by the compiler to determine the array order of an input or output

pub fn value_array_order(value: &Value) -> i32

Determine how deeply nested in arrays this serde_json::value::Value is. If not an array, returns 0

This is used at run time to determine the array order of an actual value being processed

pub fn compatible_types( from: &[DataType], to: &[DataType], from_subroute: &Route ) -> Result<()>

For a set of output types to be compatible with a destination’s set of types ALL of the output_types must have a compatible input type, to guarantee that any of the valid types produced can be handled by the destination

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataType

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

Formats the value using the given formatter.

impl Default for DataType

fn default() -> DataType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DataType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataType

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

Formats the value using the given formatter.

impl From<&str> for DataType

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for DataType

fn from(s: String) -> Self

Converts to this type from the input type.

impl FromStr for DataType

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for DataType

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 Ord for DataType

fn cmp(&self, other: &DataType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DataType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for DataType

fn partial_cmp(&self, other: &DataType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DataType

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 DataType
