Struct FunctionExtensions

pub struct FunctionExtensions {
    anchor_to_name: BTreeMap<u32, String>,
}

In Substrait, a function can be define by an u32 anchor, and the anchor can be mapped to a name

So in substrait plan, a ref to a function can be a single u32 anchor instead of a full name in string

Fields

anchor_to_name: BTreeMap<u32, String>

Implementations

impl FunctionExtensions

pub fn from_iter(inner: impl IntoIterator<Item = (u32, impl ToString)>) -> Self

pub fn try_from_proto( extensions: &[SimpleExtensionDeclaration], ) -> Result<Self, Error>

Create a new FunctionExtensions from a list of SimpleExtensionDeclaration

pub fn get(&self, anchor: &u32) -> Option<&String>

Get the name of a function by it’s anchor

pub fn to_extensions(&self) -> Extensions

Trait Implementations

impl Clone for FunctionExtensions

fn clone(&self) -> FunctionExtensions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionExtensions

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionExtensions

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FunctionExtensions

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 FunctionExtensions

fn cmp(&self, other: &FunctionExtensions) -> 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 FunctionExtensions

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

fn partial_cmp(&self, other: &FunctionExtensions) -> 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 FunctionExtensions

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 FunctionExtensions
