Enum kpal_plugin::Val

#[repr(C)]
pub enum Val {
    Int(c_int),
    Double(c_double),
    String(*const c_uchar, size_t),
    Uint(c_uint),
}

A wrapper type for transporting Values through the plugin API.

Unlike the Value enum, this type is intended to be sent through the FFI. Because of this, the enum variants can only contain C-compatible datatypes.

Variants

Int(c_int)

Double(c_double)

String(*const c_uchar, size_t)

Uint(c_uint)

Methods

impl Val

pub fn to_value(&self) -> Result<Value, ValueConversionError>

Clones the data inside a Val into a new Value type.

This method is used to convert Vals, which pass through the FFI, into owned Value datatypes. Wrapped data that is not Copy is necessarily cloned when the new Value instance is created.

Trait Implementations

impl Clone for Val

fn clone(&self) -> Val

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Val

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

Formats the value using the given formatter.

impl PartialEq<Val> for Val

fn eq(&self, other: &Val) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Val) -> bool

This method tests for !=.
