Implementations

impl Type

pub fn list(inner: Type) -> Self

pub fn one_of(types: impl IntoIterator<Item = Type>) -> Self

Creates a OneOf type from an iterator of types. Flattens any nested OneOf types and removes duplicates.

pub fn record() -> Self

pub fn table() -> Self

pub fn custom(name: impl Into<Box<str>>) -> Self

pub fn is_subtype_of(&self, other: &Type) -> bool

Determine of the Type is a subtype of other.

This should only be used at parse-time. If you have a concrete Value or PipelineData, you should use their respective is_subtype_of methods instead.

pub fn widen(self, other: Type) -> Type

Returns the supertype between self and other, or Type::Any if they’re unrelated

pub fn supertype_of(it: impl IntoIterator<Item = Type>) -> Option<Self>

Returns the supertype of all types within it. Short-circuits on, and falls back to, Type::Any.

pub fn is_numeric(&self) -> bool

pub fn is_list(&self) -> bool

pub fn accepts_cell_paths(&self) -> bool

Does this type represent a data structure containing values that can be addressed using ‘cell paths’?

pub fn to_shape(&self) -> SyntaxShape

pub fn get_non_specified_string(&self) -> String

Get a string representation, without inner type specification of lists, tables and records (get list instead of list<any>

pub fn follow_cell_path<'a>( &'a self, path_members: &'a [PathMember], ) -> Option<Cow<'a, Self>>

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Default for Type

fn default() -> Type

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Type

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Type

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

Formats the value using the given formatter.

impl From<ByteStreamType> for Type

fn from(value: ByteStreamType) -> Self

Converts to this type from the input type.

impl Hash for Type

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 Type

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Type

fn eq(&self, other: &Type) -> 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 PartialOrd for Type

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Type

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 Type

impl StructuralPartialEq for Type
