Struct FunctionSig 

pub struct FunctionSig {
    pub params: Vec<SequenceType>,
    pub ret: SequenceType,
}

The signature of a specific function test function(T1, …, Tn) as R (XPath 3.1 §2.5.4.3). Drives the function-subtyping rules applied by instance of / treat as: the parameter types are contravariant and the return type is covariant.

Fields

params: Vec<SequenceType>

ret: SequenceType

Trait Implementations

impl Clone for FunctionSig

fn clone(&self) -> FunctionSig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionSig

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

Formats the value using the given formatter.

impl PartialEq for FunctionSig

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