Struct FunctionPointer

pub struct FunctionPointer {
    pub sig: FunctionSignature,
    pub generic_params: Vec<GenericParamDef>,
    pub header: FunctionHeader,
}

A type that is a function pointer.

Fields

sig: FunctionSignature

The signature of the function.

generic_params: Vec<GenericParamDef>

Used for Higher-Rank Trait Bounds (HRTBs)

   for<'c> fn(val: &'c i32) -> i32
// ^^^^^^^

header: FunctionHeader

The core properties of the function, such as the ABI it conforms to, whether it’s unsafe, etc.

Trait Implementations

impl Clone for FunctionPointer

fn clone(&self) -> FunctionPointer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionPointer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionPointer

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FunctionPointer

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 PartialEq for FunctionPointer

fn eq(&self, other: &FunctionPointer) -> 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 Serialize for FunctionPointer

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 FunctionPointer

impl StructuralPartialEq for FunctionPointer

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
