Struct rhai::FnCallExpr

pub struct FnCallExpr {
    pub hash_script: Option<NonZeroU64>,
    pub capture: bool,

    pub namespace: Option<NamespaceRef>,
    pub name: Cow<'static, str>,

}

(INTERNALS) A function call. Exported under the internals feature only.

Volatile Data Structure

This type is volatile and may change.

Fields

hash_script: Option<NonZeroU64>

Pre-calculated hash for a script-defined function of the same name and number of parameters. None if native Rust only.

capture: bool

Does this function call capture the parent scope?

def_value: Option<Dynamic>

Default value when the function is not found, mostly used to provide a default for comparison functions.

namespace: Option<NamespaceRef>

Namespace of the function, if any. Boxed because it occurs rarely.

name: Cow<'static, str>

Function name. Use Cow<'static, str> because a lot of operators (e.g. ==, >=) are implemented as function calls and the function names are predictable, so no need to allocate a new String.

args: StaticVec<Expr>

List of function call arguments.

Trait Implementations

impl Clone for FnCallExpr

fn clone(&self) -> FnCallExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FnCallExpr

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

Formats the value using the given formatter.

impl Default for FnCallExpr

fn default() -> FnCallExpr

Returns the "default value" for a type.

impl Hash for FnCallExpr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.
