Enum Val

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

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§

Implementations§

Source§

impl Val

Source

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.
